The Year 2015 for The Power Industry

The New Year has arrived so it is time to analyze the status of power sector in India in 2015. We are bringing the glimpse of the performance of power sector in 2015 and what are the further opportunities and road-maps for the coming years. So here take a look on the power sector in India in 2015. Priyanka Roy Chaudhary 36

COVER STORY

he year 2015 has ushered in a spell of boons for the domestic power sector. The year FY15 was a good year for Indian power sector where power generation grew by 8.4% YoY and the peak deficit was down to 3.5% in FY15 from 4.5% in FY14. This was largely on the back of rising coal stock availability at majority of the power stations and increase in the installed power capacity. The year FY15 saw key reforms for the sector, they are 1) Reallocation of coal blocks through e-auction process, 2) New gas pooling mechanism to bailout 14,000 MW of stranded power plants and 3) New Ultra Mega Power Project (UMPP) policy to approach plug and play model. Also, there has been an improved focus on the T&D sector to improve the power supply conditions in the country. India approved a rescue package for its loss-making power utilities on Thursday, unveiled as a major reform that Prime Minister Narendra Modi hopes will end electricity blackouts and spur economic growth. Power Minister Piyush Goyal said states would over the next two years be allowed to take on 75 percent of the debts of their utility companies, which have grown to 4.3 trillion rupees ($65.3 billion) after years of undercharging customers for electricity. By clearing past debts and putting them on a better financial footing, Goyal said the utilities would be returned to profitability before 2019.

falling pricing of the same globally. The energy sector in India has seen a transformational change with progressive policy-level changes and effective implementation of directives. These changes promise enormous opportunities for various stakeholders and market players. However, deep thinking on various aspects of policy and regulatory interventions and their long-term implications will help in taking informed decisions and contribute in developing the sector. Energy is one of the key enablers for the country’s economic development. With the certainty in policy-level interventions, the economy is bound to propagate and the demand for energy will inevitably surge. Other than economic growth, human and develop mental aspects like poverty reduction, employment generation, etc. are also considerably dependent on secure energy supply. The power sector is a major consumer of energy and it has a significant impact one economic developments and social welfare. Per-capita electricity consumption of the country has now crossed 1,000 kilowatt-hour (kWh), but still, it is far below the average global consumption. In June 2015, all-India generation

capacity stood at 275 gigawatts (GW) with a contribution of 69% from thermal energy, 15% from hydro, 13% from renewable,and 2% from nuclear sources. The eastern region contributes 12% to the total generation capacity. Despite the efforts to generate more electrical energy by using multiple energy sources, the country has recorded a shortage of 3.6% of demand in FY15. As per the Central Electricity Authority’s (CEA) Load Generation Balance Report 2015-16, in spite of the expected capacity addition of 20 GW, the country will probably experience energy shortage. Key energy sources used for generating electricity are coal, lignite, petroleum and natural gas, renewable sources, etc. Nearly 80% of the country’s coal reserves are located in the eastern states of Bihar, Chhattisgarh, Jharkhand, Odisha and West Bengal, with the highest reserve of around 81 billion tonne in Jharkhand. India has a total reserve of an estimated 43.24 billion tonne of lignite, of which 99% is located in Tamil Nadu, Rajasthan and Gujarat. As much as 68% of crude oil reserves are in western offshore and Assam, whereas eastern offshore encompasses 7% of there serves. But it has the maximum reserve of natural gas at 37.24%, which is followed by western offshore at 30.17%. India also has a high potential for energy

Prime Minister Modi has urged the power ministry and states to find a way to overhaul the power distribution sector, whose weak finances have limited bank lending and undermined the push to provide reliable electricity in Asia’s third-largest economy.

As India’s demand grows, steps have to betaken to ensure the concerns that impede the expansion of its power sector. As are result of populist tariff schemes exacerbated by aggregate technical and commercial (AT&C) losses and operation a line efficiencies, the finances of the state discoms are becoming unhealthy with huge outstanding debt. India’s power sector also grapples with complex regulatory processes, and the high cost of financing new projects results in cost overruns, leading to a high tariff. India is trying to leverage its renewable potential by betting big on solar and wind energy, and the government has set an ambitious target for renewable sources-based power generation. The Indian power sector has come along way since the laying down of the basic framework in 1910 right up to the Electricity Act of 2003, which ||www.electricalmirror.in||

The Act introduced and brought provision on open access, power trading, regional/national electricity market, independent system operator, de-licensing of generation, performance based regulation, anti-theft etc. To govern the sector better and handle its requirement, the Electricity Amendment Bill, 2014, is under consideration. The union cabinet approved amendments to the overarching Electricity Act, 2003, through the Electricity Amendment Bill, 2014,on 11 December 2014. The proposed amendment will have a profound impact on the Indian power sector. It touches upon different aspects of the sector,right from segregation of carriage and content to renewable energy and open access to tariff rationalization and soon. It has seen a mixed response: being hailed as historic by some and, at the same time, inviting the ire of a few state governments. The bill is the segregation of distribution and supply areas, which will provide the consumer with more choices. The Bill also aims to infuse healthy competition in each distribution area, and deals with aspects pertaining to promotion of renewable energy, open access, smart grid, ancillary services and so on. Some of the amendments are seen as much-needed and address the major caveats and limitations of the Act. These proposed amendments necessitate significant reorganization of the distribution and supply businesses of existing licensees, propose significant measures for renewable energy promotion, including obligations for thermal power developers to establish renewable generation capacity and provide measures for tariff rationalization and enhancement in grid safety and security. The key intent behind the amendments is to allow competition and better customer service without significantly increasing tariff. Record capacity addition during 12th Five Year plan period: India has added highest ever power generation 40

capacity (in single five year plan) during 12th Five Year plan. So far, India has added cumulative power capacity of 61,014 MW upto March 2015 which is an achievement of ~69% (Highest in the last 4 five year plan periods) of the targeted capacity addition of 88,537 MW during the plan. This has been largely led by sharp achievement in the thermal segment which achieved ~80% of the targeted capacity addition, followed by Hydro (~21%) and balance by nuclear segment with ~19%. We think this is largely on the back of spill over from the previous plan period (partially) and increased coal availability & faster environment clearances for the various projects. Out of the total targeted capacity addition, NTPC Ltd had set a target of adding 14,038 MW (~16% of total). The company has already added ~7,000 MW which is ~50%. The management had stated the company is focused on achieving the target and likely to do so by the end of FY17.

promulgated the Coal Mines (Special Provisions) Ordinance 2014 for the management and reallocation of all the cancelled coal blocks through e-auction process. The e-auction has been done in a phased manner. So far, the Government has conducted two rounds of auctions and auctioned 23 coal blocks which is expected to garner around Rs.2 trillion to the respective state governments. We think that the reallocation of de-allocated coal blocks through e-auction process has been a very positive step by the Government for Power and Coal sector. The move is likely to ensure the steady supply of coal for the existing and upcoming power projects. In order to expedite operations from the reallocated coal blocks, the Environment Ministry has allowed transfer of environment clearances granted to the previous allottees to new owners without any fresh approval which is also a step in the right direction.

27,123 MW, of which 14,305 MW is stranded (operating at zero plant load factor (PLF)) and the balance 9,845 MW has been operating at abysmally PLF of ~30%. This has been due to significant reduction in the gas supplied to the power sector from 70.6 mmscmd in ||www.electricalmirror.in||

COVER STORY FY11 to 28.9 mmscmd in FY14 due to a decline in gas production from the KG-D6 basin. To address this issue, the Union Cabinet recently approved a path-breaking mechanism for operational zing stranded gas-based generation capacity in FY16 and FY17. The mechanism talks about importing re-gasified liquefied natural gas (RLNG) for supply to stranded power plants and plants receiving domestic gas. However, both these types of power plants can use RLNG to operate their power plant to the maximum extent of 30% PLF. Given the expensive nature of imported RLNG, the Government will be providing a subsidy, which is capped at Rs.35 bn for FY16 (includes Rs.30 bn for stranded power plants and Rs.5 bn for others) and Rs.40 bn for FY17 (includes Rs.35 bn for stranded power plants and Rs.5 bn for others). The subsidy will be funded through the Power sector development fund (PSDF). Given the large share of gas based power capacity being stranded, we think the move is positive as it is likely to help lot of companies in kick-starting these

capacities. According to Moody’s, these capacities involved a significant level of investment, at around USD 16 bn, most of which was bank financed. The total exposure of the banking 42

system to the power sector at the end of January 2015 totaled around USD 88 bn, or 9% of total outstanding bank credit. Hence, the move is also positive for banks which are likely to get their interest and debt repaid. New Ultra Mega Power Project (UMPP) policy to approach plug and play model: During the last union budget, the Government proposed New Ultra Mega Power Project (UMPP) policy to approach plug and play model. Under the “plug-and-play” mode, coal linkages and indicative green clearances are expected to be ensured to simplify mining and faster execution. The Government has announced plans to auction five new UMPPs in the plug-and-play mode to ensure their smooth execution and help “unlock” investments to the tune of Rs. 1 trillion. Weak set of numbers for Q4FY15: Power companies reported mixed set of numbers for Q4FY15 with average revenue and PAT growth of 7.6% YoY and 5.1% YoY respectively. While companies with thermal power capacity benefited due to lower fuel cost, however plant load factor for majority of these companies was lower

which impacted the revenue growth and profitability. Apart from the ambitious targets for the Thermal Power sector, the

Government has also increased its focus on the renewable energy sector. India’s current capacity from renewable sources of energy stands at 31,692 MW (End of April 2015) which is ~12% of the total installed power generation capacity. The Government’s earlier target of installing 20,000 MW of solar energy capacity by 2022 has been revised to 100,000 MW. The Government also wants to put in place 60,000 MW of wind power capacity, 10,000 MW Biomass and 5,000 MW Small Hydro capacities. Over the years, Indian power sector investments were largely focused towards increasing of power generation capacity. This has resulted in relatively under investment in Transmission and Distribution (T&D) space. This has led to high power merchant rates, power stations backing down, low PLFs at power plants due to unavailability of transmission lines and high T&D losses. As per Central Electricity Authority (CEA), India’s T&D Losses and Aggregate Technical and Commercial (AT&C) Losses stood higher at 23.04% and 25.38%, respectively in FY13. According to FICCI, overall an addition of 90,000 circuit kilometers (CKM) of 765-220 kV lines, 154,000 Megavolt Ampere (MVA) of substation capacity and 27,350 MW of national grid capacity is required in order to meet the 12th Five Year Plan. For this purpose, an investment of USD 35 bn is planned in the power transmission sector. Of this, about USD 19 bn is planned to come from Power Grid Corporation of India Limited (PGCIL). The remaining USD16 bn, ~46% of the total investments, needs to be secured from private players/ State Transmission Utilities (STUs). Separately, PGCIL has made an ambitious plan to invest more than Rs.1 trillion during the 12th plan, matching with the envisaged generation capacity addition, out of which Capital expenditure of Rs.431.95 bn has already been made in the first two years of the 12th plan period.

The Government has planned to provide affordable 24x7 power for all homes, industrial and commercial establishments and adequate power for farms by 2019. Along with generation, the Government has also increased its focus on the T&D space which is likely to help in improving PLF levels, improving financial health of SEB’s and reducing Transmission losses.

Power remains one of the most critical components of infrastructure affecting economic growth of the economy. For FY15, India’s peak deficit came in at 3.5% which is much lower than its historic average. We believe, although FY15 peak deficit was low but this was due to weak financial positions of state distribution companies. We believe with improvement in financial health of the State Electricity Board’s, demand is likely to pick up over the near to medium term. Also the Government’s focus on the manufacturing sector through its flagship initiative Make in India is likely to drive the demand high.

On the coal front The proposed doubling of green cess on coal from Rs 100 per tonne to Rs 200 for funding investment in renewable sources and clean coal technology for power plants bolsters India’s claim that it is serious about reducing greenhouse gas emissions, but at its own pace. This stands to benefit the sector quite a lot. KPMG’s whether financial five new

Manish Agarwal doubts the power sector has the capacity to invest in the showcase projects totalling

20,000MW. This doubt is natural, given that the financial sector is stressed over 16,000MW gas-fired generation capacity idling for want of fuel. The mode of draw-down of coal cess so far accumulated and expected to be mopped up has not been described. Solar power is to have the lion’s share of the renewable energy target at 1,00,000MW, followed by 60,000MW of wind energy, 10,000MW biomass and 5,000MW of small hydro projects of up to 25MW each. Solar power generation capacity right now stands at 3,000MW, accounting for 6.5% of the electricity mix. Power minister Piyush Goyal has said that India’s renewable energy sector plans to attract $200 billion in investments as many domestic and international firms have shown interest in tapping the potential of green power. The price of coal from the auctioned coal block has no correlation to the actual cost of production. Also, coal blocks earmarked for the power sector were put up for reverse auction, and awarded on the basis of the lowest transfer price quoted by the bidder.

||www.electricalmirror.in||

The new provisions provide for the replacement of coal price in the existing Power Purchase Agreement (PPA) by the price quoted, in case it results in fuel cost reduction, and therefore, the entire process is expected to lower the final power tariff.

Future Roadmap: With definite challenges of keeping the cost of fuel, i.e. coal produced from the auctioned blocks, at minimum levels by the new allottees, apart from project preparedness, the need of the hour is to look again into the existing mining practices prevailing in the country. Certainly, major reforms need to be brought in, with improvements in processes and technology as major focus areas and workplace safety on the prime agenda. A stringent projectlevel monitoring system needs to be put in place to capture variances between the budgeted and actual progress made and standard operating procedures (SOPs) need to be designed for taking immediate actions whenever

needed. Cost control measures such as optimization, improvement in productivity, utilization of existing resources, stringent and accurate data monitoring system, which we have been debating for long, need to take the front seat to keep the operating cost at the lowest levels, as these costs are not passed through to the utilities. Besides these measures, project preparedness will also play an important role. Preparing a detailed checklist for the various approvals or clearances to be obtained after the vesting order, re-validating the transferred approvals or clearances through the vesting order, selecting qualified and suitable mining contractors through a competitive bid process, distributing appropriate roles and responsibilities, employing key and statutory manpower, etc. are some of the crucial elements that the new allottees will need to adopt for successful outcomes. As part of project

preparedness itself, carrying out a â&#x20AC;&#x2DC;fatal flawâ&#x20AC;&#x2122; analysis at an early stage may be advisable to capture the mitigating measures. The role of the state in expediting approval and clearance work for development and operation of the allocated coal blocks will also be vital. Assistance in fast-track processes will certainly be important for new allottees, and primarily serve two purposesâ&#x20AC;&#x201C;follow the time lines for project development, and commence production to start generating cash flows for the project. In conclusion, a scientific and collaborative approach will be required for successful follow-up post the auction. With two rounds already concluded, questions still remain on economic viability, speedy processes and the passing on of actual benefits to consumers.

“

With advancing age transformers require regular checks of the operating conditions. Measurement of the water content in oil-paper insulation is a helpful tool for making an assessment of the ageing of the cellulose. The analysis of the gas in oil is a well-proven method of analysis but must be complemented by efforts to locate any faults indicated by excess hydrocarbon gases in the oil. This way important maintenance can be performed in time to avoid a sudden total failure. The fault location can be successfully performed using modern type test equipment for resistance, winding ratio, short circuit impedance, C, tan δ, FRA and PD measurements.

ower transformers are critical, capital-intensive assets for utilities and industry. Transformers are extremely reliable; however, many of the transformers in use today have already exceeded their design life. Today transformers are not automatically replaced, if they have reached the end of their life span, but left in service as long as possible. In contradiction to the past many power transformers are operated nowadays at or above rated power. With advancing age of power transformers, a regular check of the operative condition becomes more and more important. Several tests can be performed to determine

analysis so called DGA analysis. Also some electrical values like winding and insulation resistance, no load current or capacitance and dissipation factor (DF) at mains frequencies were measured on site periodically. Online monitoring systems were introduced to gather current data about e.g. the voltage, current or the temperature. Such systems can help to recognize rapid changes of the transformer condition very early. Not every test can be performed on line, but for example on line monitoring systems for the oil, tap changer, cooling system or the bushings are already available. Very often a set of diagnostic measurement

are needed to identify a specific fault. The most common electrical diagnostic

measurement methods are listed in table 1.

DIAGNOSTIC MEASUREMENT METHODS 1. Dielectric Response Measurement Increase of water in oil-paper insulations goes hand in hand with transformer aging, it decreases the dielectric withstand strength, accelerates cellulose decomposition and causes the emission of bubbles at high temperatures. State of the art for moisture measurements are equilibrium diagrams where one tries to derive the moisture in the solid insulation (paper, press board) from moisture in oil. This method fails for several reasons [1]. To assess the insulation’s water content some dielectric diagnostic methods were widely discussed and occasional used during the last decade. The multilayer insulation of common power transformers consists of oil and paper and therefore shows polarization and conductivity effects. Dielectric diagnostic methods work in a range dominated by inter facial polarization at the boarders between cellulose and oil, cellulose conductivity and oil conductivity. Moisture influences these phenomena. Temperature and the insulation construction have a strong impact too. In [2] a comparison of the mentioned methods was analysed. ||www.electricalmirror.in||

FDS and PDC methods give rather reliable results and reflect also the influence of the temperature and the geometry by using an X-Y model. The results of the PDC measurement can be transformed from the time domain into the frequency domain [3], [4] and [5]. Although the results of PDC and FDS methods are comparable and can be transformed from the time domain into the frequency domain and vice versa, both methods have advantages and disadvantages. If the FDS shall be used down to 100uHz, a measuring time of up to twelve hours is needed for one measurement e.g. the insulation gap between HV and LV winding. If also other insulation gaps e.g. HV winding to tank or LV to TV winding shall be measured, even more time is necessary. The PDC measurement needs much less time but is limited to frequencies up to about 1Hz. A new approach combines both methods [6]. The FDS measurement is replaced by the PDC method in the low frequency range and the results are transformed into the frequency domain, whereas the FDS is used for higher frequencies, which can be done rather quickly.

model curves for new oil-pressboard insulation which were used up to date. 2. Winding Resistance Measurement and OLTC Test Winding resistances are measured in the field to check for loose connections, broken strands and high contact resistance in tap changers. Additionally, the dynamic resistance measurement enables an analysis of the transient switching operation of the diverter switch. In most cases, the tap changer consists in most cases of two units. The first unit is the tap selector, which is located inside the transformer tank and switches to the next higher or lower tap without carrying current. The second unit is the diverter switch, which switches without any interruption from one tap to the next while carrying load current. The commutation resistances R or inductors L limit the short circuit current between the taps which could otherwise become very high due to the switching of the diverter contacts without during the period, where both taps are connected. The switching process between two taps takes approximately 40-80 milliseconds.

Dynamic Behavior of the Diverter Switch In the past only the static behavior of the contact resistances has been taken into account in maintenance testing. With a dynamic resistance measurement, the dynamic behavior of the diverter switch can be analyzed (figure 1) [8]. For the dynamic resistance measurement, the test current should be as low as possible Figure 1: Dynamic resistance measurement otherwise short interruptions or bouncing of the diverter switch contacts cannot be Two input channels for simultaneous detected. In this case, the initiated arc measurement of two insulation gaps has the effect of shortening the open make it even faster. New model curves contacts internally.

(di/dt) of the measured current, as these are important criteria for correct switching. If the switching process is interrupted, even for less than 500us, the ripple and the slope of the current change dramatically. 3. Frequency Response of Stray Losses (FRSL) The frequency response measurement of stray losses is a tool to determine short circuits of parallel strands. The resistive part of the short circuit impedance is measured over a frequency range from 15Hz up to 400Hz. The resistance curves of the three phases are compared. The 15Hz values are very close to the DC values of the primary winding resistance plus the resistance of the secondary winding multiplied by the square of the ratio. If the curve of one phase is more than 2-3% different from the other phases a short circuit fault between parallel strands can be the reason for this behavior. Local overheating can cause dangerous breakdowns this behavior. Local overheating can cause dangerous breakdowns 4. Capacitance and Dissipation Factor (tan δ) Measurement In the past, the dissipation or power factor was measured at line frequency only. With the described test system it is now possible to make these insulation measurements in a wide frequency range. Beside the possibility to apply frequency sweeps, measurements can be made at frequencies different from the line frequency and their harmonics. With this principle, measurements are possible also in the presence of high electromagnetic interference in high voltage substations.

Dissipation Factor (DF) Measurements on High-voltage Bushings Bushings with high moisture in the insulation show increased 50/60Hz tan δ values particularly at higher temperatures.

by measuring the electrical transfer functions over a wide frequency range. This is usually done by injecting a low voltage signal of variable frequency into one terminal of a transformers winding and measuring the response signal on another terminal. This is performed on all accessible windings following according guidelines. The comparison of input and output signals generates a frequency response which can be compared to reference data, to other phases, or to sister transformers (figure 4).

Geometrical changes within and between the windings change mainly the capacitor elements of the network and cause deviations in its frequency response. Differences between an FRA fingerprint and the result of an actual measurement are an indication of electrical variations of the components of the equivalent circuit diagram. Different failure modes affect different parts of the frequency range and can usually be discerned from each other.

Therefore the handling of disturbances is one of the main tasks when measuring PD. A new field of evaluation methods is opened by fully synchronous multichannel PD acquisition in order to gain more reliable measuring results combined with effective noise suppression. A technical overview of the system is given in [11]. Being able to perform synchronous multi-channel PD measurements, the Three-Phase-Amplitude-RatioDiagram (3PARD) was introduced

as a new powerful analysis tool to distinguish between different PD sources and noise pulses when measuring high voltage equipment such as power transformers, rotating machines and cable systems. Responses of the PD are received simultaneously at three different positions of the measurement circuit. The amplitudes of three PD channels are geometrically added like vectors in a star diagram, where the three axes are corresponding to the three channels. A PD source corresponds normally to an amplitude ratio of the three responses which is defined by the coupling of the PD signal into the three channels. Noise is normally more or less received with similar amplitude responses from the three channels. The addition of the three similar noise signals gives a position close to the star point of the 3PARD.

Shailendra Goyal - M.D. - Zera India Pvt. Ltd.

Success is a diminutive word to justify our achievements. ZERA India came into existence 10 years back, it’s a small time to achieve so much of name and fame in Energy Meter testing industry. We are highly obliged to our customers who trust us since long time. ZERA India, a German Subsidiary in India responsible for South East Market. ZERA GmbH has expanded its wings in 2006 by establishing office in India for further expansion in research, development and manufacturing of equipments to provide our customers unequalled testing solutions which can full fill indigenous market requirements. To be the paragon of this field our key factors are; our assiduous team who constantly work to achieve our mission to design equipments for helping utilities to construct and establish modern testing facilities, our operations and strategies to achieve this mission, physical resources and best quality product and last but certainly not the least our customers who had shown so much trust in our products and who constantly encourage us to develop new technologies to full fill the emerging requirement for Smart Metering . As the famous business guru Peter Drucker said, “The purpose of a business is to get and keep customers”. We understand the needs of our 64

customers and provide a lucid detail about products and help to resolve their problems. The services provided by us made the name of ZERA perennial in customer’s minds. And without belaboring much I can proudly say that we serve our customers in competent and efficient manner in the area related to application, calibration & technical services.

experience. On this basis, we have been developing and producing test systems for many years- systems that deliver reliable and reproducible results of highest precision with complete safety to our clients. ZERA is committed to the quality seal “Made in Germany” and our customers appreciate this. This is why our products have been able to prevail worldwide.

How do you ensure the complete safety of your products to your clients?

Up to now, Meter testing was only testing of the metrology. But with the introduction of Smart Meters, the aspect of data communication has come more and more into the focus of testing. It is no longer sufficient for a meter only to register the correct values. The correct transmission of data and its accuracy and consistency is equally important. So VDE, Germany & ZERA developed a concept for new test system in joint project work. Unlike all, currently at the market available test systems, this one can test functionality of smart digital meters as well as data communication. ZERA has developed in co operation with partners, a test system for metrology & data communication named SML protocol. The Smart Meter Language protocol serves for transmitting data between the meter & the remote meter reading system. This protocol for remote meter reading possesses an optimized structure for use in both classical communication routes and in package- oriented network operation. ZERA is also working for IEC standards which are the demands of the day.

How do you see the current trends and market of testing industry in India?

The testing and calibration industries in India have developed in a quite short duration & are of International standards. We can see the large potential in this field both nationally and globally. Due to the power scenario, Indian market is much more promising for Energy Management. Electrical Engineering is often an intriguing science as the electricity cannot be seen. However, we all are aware of its existence and usefulness in our daily lives. The future of Energy monitoring and measurement system in India is rapidly moving towards the integration of smart meters for energy management purposes it is becoming dynamic and experiencing volatility. Indian government is readily taking steps to thrive technologies in market. One such gigantic event which would showcase the people, policies and partnerships that are driving India’s new manufacturing revolution is going to be held in month of Feburary’2016 “MAKE IN INDIA”, which will boost India’s GDP, trade and economic growth by manufacturing products in India. Indian market is steadily moving towards a newer generation of equipment which includes hi-tech and precision measurable system by adopting some newer technologies and modernizes technologies that are adopted.

Global market has already settled itself in field of test and measurement sector (T& M) as compared to Indian market. The European market aims to replace at least 80% of electricity meters with smart meters by 2020 wherever it is cost effective to do so. This smart metering rollout can reduce emissions in Europe up to 9% and annual household energy consumption by similar amount, it is expected that by 2020 almost 72% of European consumers will have a smart Meter for electricity. But with this I want to append that the highly dynamic Indian Electricity Market is aggressively invigorating, to keep pace with the rapidly changing technical requirements of end users. We are focussing to develop Testing and measuring products here itself in India to join the fire ignited by our Prime Minister Narendra Modi. This will definitely boom the current trends & market of measuring & testing industry in India.

What are your plans and expectations from Elecrama? What are the products you are going to showcase at Elecrama?

Elecrama 2016” It is a biggest & premier event in Indian electrical sector and is the world largest confluence of the power transmission and distribution community, held biennially since 1990 in India. In last 2 decades Elecrama as an exhibition featured the biggest names in global electrical T&D industry, to which it serves as a perfect platform to introduce latest products and technologies. We have our stall (H2J27) in Indo German chambers, where ZERA India is planning to display our newly launched products MTi100 hand held working standard based on state of art technology in power measurement, MTi300 three phase working standard with accuracy class 0.2 in direct mode and 0.5 in clamp on CT mode; ZERA comparator COM5003 having striking feature 0.005% accuracy class. Our expectation is to concoct lucid the picture of meter testing equipments and the benefits possessed by it, plus

to explore and expand the business in entire world by providing a reliable and hi tech measurement solutions for Energy meters to the manufacturers, Laboratories & Power utilities. New and interesting additions are made in Elecrama 2016 like “Network2Network” is planned for creating awareness about the huge investment and opportunities in Indian electrical sector for both global and domestic investors. These eye catching events will help to flourish our expectations. We will divulge more details at the time of Exhibition.

According to you what are the current major challenges in Industry?

Accuracy and reliability has always been significant. But now, with the liberalization of the energy market, it is getting even more essential. There is no longer a single relationship between one supplier and one customer. Instead the network is divided into the hands of several parties that produce, transmit, consume and those who cover more than one aspect. The rapidly mounting testing & calibration infrastructure in India has gained international standards; still some milestones are need to be achieved • As per CEA guideline distribution companies shall have an appropriate number of accredited Meter testing laboratories from NABL. • Consumer’s meter shall be tested at least once in 5 years. The meters may be tested using NABL accredited mobile laboratory or at any accredited laboratory. • Financial health of state electricity boards, high aggregate technical and commercial losses, is adding up the challenges in Energy and Power distribution segment. • T & M sector uses poor quality of equipments for their measuring unit due to which consumption and losses cannot be measured precisely. So awareness about quality of equipment is needed. • Plus some utilities are using archaic Meter testing system which are not appropriate to diagnose the quality ||www.electricalmirror.in||

CAPACITOR & CONDENSER

A Detailed Study on Shunt Capacitor Bank Fundamentals and Protection INTRODUCTION Shunt capacitor banks (SCB) are mainly installed to provide capacitive reactive compensation/power factor correction. The use of SCBs has increased because they are relatively inexpensive, easy and quick to install and can be deployed virtually anywhere in the network. Its installation has other beneficial effects on the system such as: improvement of the voltage at the load, better voltage regulation (if they were adequately designed), reduction of losses and reduction or postponement of investments in transmission. The main disadvantage of SCB is that its reactive power output is proportional to the square of the voltage and consequently when the voltage is low and the system need them most, they are the least efficient. Shunt capacitor banks are used to improve the quality of the electrical supply and the efficient operation of the power system. Studies show that a flat voltage profile on the system can significantly reduce line losses. Shunt capacitor banks are relatively inexpensive and can be easily installed anywhere on the network.

some knowledge of the capabilities and limitations of the capacitor unit and associated electrical equipment including: individual capacitor unit, bank switching devices, fuses, voltage and current sensing devices. Capacitors are intended to be operated at or below their rated voltage and frequency as they are very sensitive to these values; the reactive power generated by a capacitor is proportional to both of them (kVar - 27c f V 2). The IEEE Std 18-1992 and Std 1036-1992 specify the standard ratings of the capacitors designed for shunt connection to ac systems and also provide application guidelines.

These standards stipulate that: Capacitor units should be capable of continuous operation up to 110% of rated terminal rms voltage and a crest voltage not exceeding 1.2 x .\12 of rated rms voltage, including harmonics but excluding transients. The capacitor should also be able to carry 135% of nominal current. Capacitors units should not give less than 100% nor more than 115% of rated reactive power at rated sinusoidal voltage and frequency.

This paper reviews principles of shunt capacitor bank design for substation installation and basic protection techniques. The protection of shunt capacitor bank includes: a) protection against internal bank faults and faults that occur inside the capacitor unit; and, b) protection of the bank against system disturbances.

THE CAPACITOR UNIT AND BANK CONFIGURATIONS

Capacitor units should be suitable for continuous operation at up to 135%of rated reactive power caused by the combined effects of: Voltage in excess of the nameplate rating at fundamental frequency, but not over 110% of rated rms voltage.

Fig 1 â&#x20AC;&#x201D; The capacitor Unit

2.1 The Capacitor Unit The capacitor unit, Fig. 1, is the building block of a shunt capacitor bank. The capacitor unit is made up of individual capacitor elements, arranged in parallel/ series connected groups, within a steel enclosure. The internal discharge device is a resistor that reduces the unit residual voltage to 50V or less in 5 min. Capacitor units are available in a variety of voltage ratings (240 V to 24940V) and sizes (2.5 kvar to about 1000 kvar). 2.1.1 Capacitor unit capabilities Relay protection of shunt capacitor banks requires 70

Harmonic voltages superimposed on the fundamental frequency.

Reactive power manufacturing tolerance of up to 115% of rated reactive power. 2.2 Bank Configurations The use of fuses for protecting the capacitor units and it location (inside the capacitor unit on each element or outside the unit) is an important subject in the design of SCBs. They also affect the failure mode of the capacitor unit and influence the design of the bank protection. Depending on the application any of the following configurations are suitable for shunt capacitor banks: ||www.electricalmirror.in||

The capacitor unit can be designed for a relatively high voltage because the external fuse is capable of interrupting a high-voltage fault. Use of capacitors with the highest possible voltage rating will result in a capacitive bank with the fewest number of series groups. A failure of a capacitor element welds the foils together and short circuits the other capacitor elements connected in parallel in the same group. The remaining capacitor elements in the unit remain in service with a higher voltage across them than before the failure and an increased in capacitor unit current. If a second element fails the process repeats itself resulting in an even higher voltage for the remaining elements. Successive failures within the same unit will make the fuse to operate, disconnecting the capacitor unit and indicating the failed one. Externally fused SCBs are configured using one or more series groups of parallel-connected capacitor units per phase (Fig. 2). The available unbalance signal level decreases as the number of series groups of capacitors is increased or as the number of capacitor units in parallel per series group is increased. However, the kiloVar rating of the individual capacitor unit may need to be smaller because a minimum number of parallel units are required to allow the bank to remain in service with one fuse or unit out. b) Internally Fused Each capacitor element is fused inside the capacitor unit. The fuse is a simple piece of wire enough to limit the current and encapsulated in a wrapper able to withstand the heat produced by the arc. Upon a capacitor element failure, the fuse removes the affected element only. The other elements, connected in parallel in the same group, remain in service but with a slightly higher voltage across them. Fig. 3 illustrates a typical capacitor

Fig 3 â&#x20AC;&#x201D; Internally fused shunt capacitor bank and capacitor unit bank utilizing internally fused capacitor units. In general, banks employing internally fused capacitor units are configured with fewer capacitor units in parallel and more series groups of units than are used in banks employing externally fused capacitor units. The capacitor units are normally large because a complete unit is not expected to fail.

Fuseless Shunt Capacitor Banks The capacitor units for fuseless capacitor banks are identical to those for externally fused described above. To form a bank, capacitor units are connected in series strings between phase and neutral, shown in Fig. 4. The protection is based on the capacitor e l e m e n t s (within the unit) failing

When the capacitor element fails it welds and the capacitor unit remains in service. The voltage across the failed capacitor element is then shared among all the remaining capacitor element groups in the series. For example, is there are 6 capacitor units in series and each unit has 8 element groups in series there is a total of 48 element groups in series. If one capacitor element fails, the element is shortened and the voltage on the remaining elements is 48/47 or about a 2% increase in the voltage. The capacitor bank continues in service; however, successive failures of elements will lead ||www.electricalmirror.in||

CAPACITOR & CONDENSER to the removal of the bank. The fuseless design is not usually applied for system voltages less than about 34.5 kV. The reason is that there shall be more than 10 elements in series so that the bank does not have to be removed from service for the failure of one element because the voltage across the remaining elements would increase by a factor of about E (E — 1), where E is the number of elements in the string. The discharge energy is small because no capacitor units are connected directly in parallel. Another advantage of fuseless banks is that the unbalance protection does not have to be delayed to coordinate with the fuses. d) Unfused Shunt Capacitor Banks Contrary to the fuseless configuration, where the units are connected in series, the unfused shunt capacitor bank uses a series/parallel connection of the capacitor units. The unfused approach would normally be used on banks below 34.5 kV, where series strings of capacitor units are not practical, or on higher voltage banks with modest parallel energy. This design does not require as many capacitor units in parallel as an externally fused bank.

3. CAPACITOR BANK DESIGN The protection of shunt capacitor banks requires understanding the basics of capacitor bank design and capacitor unit connections. Shunt capacitors banks are arrangements of series/ paralleled connected units. Capacitor units connected in paralleled make up a group and series connected groups form a single-phase capacitor bank. As a general rule, the minimum number of units connected in parallel is such that isolation of one capacitor unit in a group should not cause a voltage unbalance sufficient to place more than 110% of rated voltage on the remaining capacitors of the group. Equally, the minimum number of series connected groups is that in which the complete bypass of the group does not subject the others remaining in service to a permanent overvoltage of more than 110%. The maximum number of capacitor units that may be placed in parallel per group is governed by a different consideration. When a capacitor bank unit fails, other capacitors in the same parallel group contain some amount of charge. This charge will drain off as a high frequency transient current that flows through the failed capacitor unit and its fuse. The fuse holder and the failed capacitor unit should withstand this discharge transient. The discharge transient from a large number of paralleled capacitors can be severe enough to rupture the failed capacitor unit or the expulsion fuse holder, which may result in damage to adjacent units or cause a major bus fault within the bank. To minimize the probability of failure of the expulsion fuse holder, or rupture of the capacitor case, or both, the standards impose a limit to the total maximum energy stored in a paralleled connected group to 4659 kVar. In order not to violate this limit, more 74

capacitor groups of a lower voltage rating connected in series with fewer units in parallel per group may be a suitable solution. However, this may reduce the sensitivity of the unbalance detection scheme. Splitting the bank into 2 sections as a double Y may be the preferred solution and may allow for better unbalance detection scheme. Another possibility is the use of current limiting fuses. The optimum connection for a SCB depends on the best utilization of the available voltage ratings of capacitor units, fusing, and protective relaying. Virtually all substation banks are connected wye. Distribution capacitor banks, however, may be connected wye or delta. Some banks use an H configuration on each of the phases with a current transformer in the connecting branch to detect the unbalance. 3.1 Grounded Wye-Connected Banks Grounded wye capacitor banks are composed of series and parallel-connected capacitor units per phase and provide a low impedance path to ground. Fig. 5 shows typical bank arrangements.

Advantages of the grounded capacitor banks include: • Its low-impedance path to ground provides inherent self-protection for lightning surge currents and gives some protection from surge voltages. Banks can be operated without surge arresters taking advantage of the capability of the capacitors to absorb the surge. • Offer a low impedance path for high frequency currents and so they can be used as filters in systems with high harmonic content. However, caution shall be taken to avoid resonance between the SCB and the system. • Reduced transient recovery voltages for circuit breakers and other switching equipment.

Some drawbacks for grounded wye SCB are: • Increased interference on telecom circuits due to harmonic circulation. • Circulation of inrush currents and harmonics may cause misoperations and/or over-operation on protective relays and fuses. • Phase series reactors are required to reduce voltages appearing on the CT secondary due to the effect of high frequency, high amplitude currents.

Multiple units grounded single Wye

Fig. 5 - Grounded Wye Shunt Capacitor Banks double wye are similar to a grounded single wye bank. The two neutrals should be directly connected with a single connection to ground. The double Wye design allows a secure and faster unbalance protection with a simple uncompensated relay because any system zero sequence component affects both wyes equally, but a failed capacitor unit will appear as un unbalanced in the neutral. Time coordination may be required to allow a fuse, in or on a failed capacitor unit, to blow. If it is a fuseless design, the time delay may be set short because no fuse coordination is required. If the current through the string exceeds the continuous current capability of the capacitor unit, more strings shall be added in parallel.

Capacitor units with external fuses, internal fuses, or no fuses (fuseless or unfused design) can be used to make up the bank. For unbalance protection schemes that are sensitive to system voltage unbalance, either the unbalance protection time delay shall be set long enough for the line protections to clears the system ground faults or the capacitor bank may be allowed to trip off for a system ground fault. b) Multiple units in series phase to neutral-double wye When a capacitor bank becomes too large for the maximum

Delta-connected banks are generally used only at distributions voltages and are configured with a single series group of capacitors rated at line-to-line voltage. With only one series group of units no over voltage occurs across the remaining capacitor units from the isolation of a faulted capacitor unit. Therefore, unbalance detection is not required for protection and they are not treated further in this paper. 3.4 H Configuration Some larger banks use an H configuration in each phase with a current transformer connected between the two legs to compare the current down each leg. As long as all capacitors are normal, no current will flow through the current transformer. If a capacitor fuse operates, some current will flow through the current transformer. This bridge connection can be very sensitive. This arrangement is used on large banks with many capacitor units in parallel.

4. CAPACITOR BANK PROTECTION The protection of SCBâ&#x20AC;&#x2122;s involves: a) protection of the bank against faults occurring within the bank including those inside the capacitor unit; and, b) protection of the bank against system disturbances and faults. This paper only discusses relay based protection schemes that provide alarm to indicate an unbalance within the bank and initiate a shutdown of the bank in case of faults that may lead to catastrophic failures. It does not deal with the means and strategies to protect individual elements or capacitor units. The protection selected for a capacitor bank depends on bank configuration, whether or not the capacitor bank is grounded and the system grounding. 4.1 Capacitor Unbalance Protection

healthy capacitor units. Unbalance protection normally provides the primary protection for arcing faults within a capacitor bank and other abnormalities that may damage capacitor elements/ units. Arcing faults may cause substantial damage in a small fraction of a second. The unbalance protection should have minimum intentional delay in order to minimize the amount of damage to the bank in the event of external arcing. In most capacitor banks an external arc within the capacitor bank does not result in enough change in the phase current to operate the primary fault protection (usually an over current relay) The sensitivity requirements for adequate capacitor bank protection for this condition may be very demanding, particularly for SBC with many series groups. The need for sensitive resulted in the development of unbalance protection where certain voltages or currents parameters of the capacitor bank are monitored and compared to the bank balance conditions. Capacitor unbalance protection is provided in many different ways, depending on the capacitor bank arrangement and grounding. A variety of unbalance protection schemes are used for internally fused, externally fused, fuseless, or unfused shunt capacitor.

Capacitor Element Failure Mode For an efficient unbalance protection it is important to understand the failure mode of the capacitor element. In externally fused, fuseless or unfused capacitor banks, the failed element within the can is short-circuited by the weld that naturally occurs at the point of failure (the element fails short-circuited). This short circuit puts out of service the whole group of elements, increasing the voltage on the remaining groups. Several capacitor elements breakdowns may occur before the external fuse (if exists) removes the entire unit. The external fuse will operate when a capacitor unit becomes essentially short

The protection of shunt capacitor banks against internal faults involves several protective devices/ elements in a coordinated scheme. Typically, the protective elements found in a SCB for internal faults are: individual fuses (not discuss in this paper), unbalance protection to provide alarm/ trip and over current elements for bank fault protection. Removal of a failed capacitor element or unit by its fuse results in an increase in voltage across the remaining elements/ units causing an unbalance within the bank. A continuous over voltage (above 1.1 pu) on any unit shall be prevented by means of protective relays that trip the bank. Unbalance protection normally senses changes associated with the failure of a capacitor element Fig. 7 â&#x20AC;&#x201C; Compensating failures in the same phase result in no unbalance signal or unit and removes the bank from service when the resulting over voltage becomes excessive on the remaining 78

circuited, isolating the faulted unit. Internally fused capacitors have individual fused capacitor elements that are disconnected when an element breakdown occurs (the element fails opened). The risk of successive faults is minimized because the fuse will isolate the faulty element within a few cycles. The degree of unbalance introduced by an element failure is less than that which occurs with externally fused units (since the amount of capacitance removed by blown fuse is less) and hence a more sensitive unbalance protection scheme is required when internally fused units are used.

Schemes with Ambiguous Indication A combination of capacitor elements/ units failures may provide ambiguous indications on the conditions of the bank. For instance, during steady state operation, negligible current flows through the current transformer between the neutrals of an ungrounded wye-wye capacitor bank for a balanced bank, and this condition is correct. However, the same negligible current may flow through this current transformer if an equal number of units or elements are removed from the same phase on both sides of the bank (Fig. 7). This condition is undesirable, and the indication is obviously ambiguous. Where ambiguous indication is a possibility, it is desirable to have a sensitive alarm (preferably one fuse operation for fused banks or one faulted element for fuseless or unfused banks) to minimize the probability of continuing operation with canceling failures that result in continuing, undetected over voltages on the remaining units. It may also be desirable to set the trip level based on an estimated number of canceling failures in order to reduce the risk of subjecting capacitor units to damaging voltages and requiring fuses to operate above their voltage capability when canceling failures occur.

Undetectable Faults For certain capacitor bank configurations some faults within the bank will not cause an unbalance signal and will go undetected. For example: a) rack-to-rack faults for banks with two series groups connected phaseover-phase and using neutral voltage or current for unbalance protection; and,b) rack-to-rack faults for certain H-bridge connections.

system voltage unbalance and capacitor manufacturing tolerance. Secondary unbalance errors are introduced by sensing device tolerances and variation and by relative changes in capacitance due to difference in capacitor unit temperatures in the bank. If the inherent unbalance error approaches 50% of the alarm setting, compensation should be provided in order to correctly alarm for the failure of one unit or element as specified. In some cases, a different bank connection can improve the sensitivity without adding compensation. For example, a wye bank can be split into a wye-wye bank, thereby doubling the sensitivity of the protection and eliminating the system voltage unbalance effect. A neutral unbalance protection method with compensation for inherent unbalance is normally required for very large banks. The neutral unbalance signal produced by the loss of one or two individual capacitor units is small compared to the inherent unbalance and the latter can no longer be considered negligible. Unbalance compensation should be used if the inherent unbalance exceeds one half of the desired setting. Harmonic voltages and currents can influence the operation of the unbalance relay unless power frequency band-pass or other appropriate filtering is provided.

Unbalance Trip Relay Considerations The time delay of the unbalance relay trip should be minimized to reduce damage from an arcing fault within the bank structure and prevent exposure of the remaining capacitor units to over voltage conditions beyond their permissible limits. The unbalance trip relay should have enough time delay to avoid false operations due to inrush, system ground faults, switching of nearby equipment, and non-simultaneous pole operation of the energizing switch. For most applications, 0.1s should be adequate. For unbalance relaying systems that would operate on a system voltage

Inherent Unbalance and System Unbalance In practice, the unbalance seen by the unbalance relay is the result of the loss of individual capacitor units or elements and the inherent system and bank unbalances. The primary unbalance, which exists on all capacitor bank installations (with or without fuses), is due to ||www.electricalmirror.in||

unbalance, a delay slightly longer than the upstream protection fault clearing time is required to avoid tripping due to a system fault. Longer delays increase the probability of catastrophic bank failures. ELECTRICAL MIR ROR || JANUARY 2016

CAPACITOR & CONDENSER With grounded capacitor banks, the failure of one pole of the SCB switching device or a single phasing from a blown bank fuse will allow zero sequence currents to flow in system ground relays. Capacitor bank relaying, including the operating time of the switching device, should be coordinated with the operation of the system ground relays to avoid tripping system load. The unbalance trip relay scheme should have a lockout feature to prevent inadvertent closing of the capacitor bank switching device if an unbalance trip has occurred. t) Unbalance Alarm Relay Considerations To allow for the effects of inherent unbalance within the bank, the unbalance relay alarm should be set to operate at about one-half the level of the unbalance signal determined by the calculated alarm condition based on an idealized bank. The alarm should have sufficient time delay to override external disturbances. 4.1.1 Unbalance Protection Methods for Ungrounded Wye Banks a) Unbalance Protection for Ungrounded Single Wye

lowest voltage ratio attainable, while still being able to withstand transient and continuous over voltage conditions to obtain the maximum unbalance detection sensitivity. However, a voltage transformer used in this application should be rated for full system voltage because the neutral voltage can under some conditions rise to as high as 2.5 per unit during switching. An equivalent zero sequence component that eliminate the system unbalances can be derived utilizing three voltage-sensing devices with their high side voltage wye-connected from line to ground, and the secondaries connected in a broken delta. The voltage source VTs can be either at a tap in the capacitor bank or used the VTs of the bank bus. Figs. 8 (b) shows a neutral unbalance relay protection scheme for an ungrounded wye capacitor bank, using three phase-to-neutral voltage transformers with their secondaries connected in broken delta to an over voltage relay. Compared to the scheme in Fig. 8(a), this scheme has the advantage of not being sensitive to system voltage unbalance. Also, the unbalance voltage going to the over voltage relay is three times the neutral voltage as obtained from Fig 8(a). For the same voltage transformer ratio, there is a gain of three in sensitivity over the single neutral-toground voltage transformer scheme. The voltage transformers should be rated for line-to-line voltage.

Modern digital relays can calculate the zero sequence voltage from the phase voltages as shown in Fig 9 (a), eliminating the need of additional Fig. 9 (a) Fig. 9 (b) auxiliary VTs to obtain the zero sequence voltage. Fig 9 (b) shows the same principle but using the VTs on the capacitor bank bus. Although schemes shown in Fig Banks 8(b), 9(a) and 9(b) eliminate system unbalances, they do The simplest method to detect unbalance in single not eliminate the inherent capacitor unbalance. ungrounded Wye banks is to measure the bank Fig. 10 shows a neutral or zero sequence voltage. If the capacitor protection scheme bank is balanced and the system voltage is balance that removes the the neutral voltage will be zero. A change in any system unbalance phase of the bank will result in a neutral or zero and compensate for sequence voltage. the inherent capacitor Fig. 8 (a) shows a method that measures the voltage between capacitor neutral and ground using a VT and an over voltage relay with 3th harmonic filter. It is simple but suffers in presence of system voltage unbalances and inherent unbalances. The voltage-sensing device is generally a voltage transformer but it could be a capacitive potential device or resistive potential device. The voltage-sensing device should be selected for the 80

The difference voltage between the neutral unbalance signal due to system unbalance and the calculated zero sequence from the terminal VTs will be compensated for all conditions of system unbalance.

However, the current transformer ratio and relay rating may be selected for the desired sensitivity because they are not subjected to switching surge currents or single-phase currents as they are in the grounded neutral scheme. Although a low-ratio voltage transformer would be desirable, a voltage transformer rated for system voltage is required for the ungrounded neutral. Therefore, a high turns ratio should be accepted.

connection between the capacitor bank neutral and ground. This current transformer has unusual high over voltage and current requirements. The ratio is selected to give both adequate over current capability and appropriate signal for the protection. The current transformer output has a burden resistor and a sensitive voltage relay. Because of the presence of harmonic currents (particularly the third, a zero sequence harmonic that flows in the neutral-to-ground connection), the relay should be tuned to reduce its sensitivity to frequencies other than the power frequency. The voltage across the burden resistor is in phase with the neutral-to-ground current. This neutral-to-ground current is the vector sum of the three-phase currents, which are 90° out of the phase with the system phase-toground voltages. This scheme may be compensated for power system voltage unbalances, by accounting for the 90° phase shift, and is not unusually appropriate for very large capacitor banks requiring very sensitive settings. Each time the capacitor bank is energized, momentary unbalanced capacitor charging currents will circulate in the phases and in the capacitor neutral. Where a parallel bank is already in service these current can be on the order of thousands Amps causing the relay to maloperate and CT to fail.

is required. They should be sized for single-phase load currents if possible. (Alternatively, the connections from neutral to ground from the two wyes may be in opposite directions through a single-window current transformer). c) Voltage differential protection method for grounded wye banks On large SCBs with large number of capacitor units, it is very difficult to detect the loss of 1 or 2 capacitor units as the signal produced by the unbalance is buried in the inherent bank unbalance. The voltage differential provides a very sensitive and efficient method to compensate for both system and inherent capacitor bank unbalances in

errors introduced by sensing device variation and temperature differences between capacitor units within the bank.

The scheme uses two voltage transformers per phase: one connected to a tap on the capacitor bank; the other, at the bank bus for single Wye banks; or, for double Wye banks, at a similar tap on the second bank. By comparing the voltages of both VTs, a signal responsive to the loss of individual capacitor elements or units is derived.

If the bank is tapped at the midpoint the sensitivity is the same for failures within and outside the tapped portion. If the bank is tapped below (above) the midpoint, the sensitivity for failures within the tapped portion will be greater (less) than for failures outside the tap portion. This difference may cause difficulty in achieving an appropriate relay setting. The sensitivity for a midpoint tap and a tap across low-voltage capacitors at the neutral end of the phase is the same. Tapping across the bottom series groups or a midpoint tap is not appropriate for fuseless banks with multiple strings because the strings are not connected to each other at the tap point. Tapping across the low-voltage capacitors is suitable for fuseless capacitor banks.

The capacitor bank tap voltage is obtained by connecting a voltagesensing device across the ground end parallel group (or groups) of capacitors. This may be a midpoint tap, where the voltage is measured between the midpoint of the phase Fig. 15 — Voltage Differential Scheme for Grounded Single Wye SCB 4.2 Protection against Other Internal and ground.

If the system voltage exceeds the capacitor capability the bank should be removed from service. The removal of the capacitor bank lowers the voltage in the vicinity of the bank reducing the overvoltage on other system equipment. Time delayed or inverse time delayed phase overvoltage relays are used.

The protection of shunt capacitor banks uses simple, well known relaying principles such as overvoltage, overcurrents. However, it requires the protection engineer to have a good understanding of the capacitor unit, its arrangement and bank design issues before embarking in its protection. Unbalance is the most important protection in a shunt capacitor bank, as it provides fast and effective protection to assure a long and reliable life for the bank. To accomplish its goal, unbalance protection requires high degree of sensitivity that might be difficult to achieve. The main concepts for the design of a shunt capacitor bank and its protection have been reviewed in the paper. The latest IEEE Guide for the Protection of Shunt Capacitors Banks shall be the guiding document when implementing a protection scheme to a shunt capacitor bank.

4.4 Relays for Bank Closing Control Once disconnected from the system a shunt capacitor bank cannot be re-inserted immediately due to the electrical charge trapped within the capacitor units, otherwise catastrophic damage to the circuit breaker or switch can occur. To accelerate the discharge of the bank, each individual capacitor unit has a resistor to discharge the trapped charges within 5min. Undervoltage or undercurrent relays with timers are used to detect the bank going out of service and prevent closing the breaker until the set time has elapsed.

Wires and Cables Industry in The India

ires and cables industry in the India is largely driven by demand from retail segment and investment level of government, registered revenues of INR ~ million in FY’2013. With an advent of new wires and cables manufacturers in the industry, the revenues increased by 14.5% compared to FY’2013 where the total revenues was INR ~ million. Each segment in the wires and cables industry such as power cables, control cables, communication cables and others is subject to a gamut of different factors such as price cuts and number of units sold that play an important role in determining their respective revenues. The wires and cables market in India comprises nearly 40 per cent of the electrical industry. According to industry experts, it is expected to double in size in the next five years. The industry is growing at a compound annual growth rate (CAGR) of 15 per cent. The market has been growing steadily, and according to a recent research, it is expected to touch Rs 572 billion by 2018. The

increasing importance of power, light and communication has kept the demand high for wires and cables. This trend will continue as demand for reliable, efficient energy and data communications will strengthen the wires and cables industry in the future as well. As the new government is focusing on ‘Make in India’, the industry can grow at a similar rate for the next five years. Every conductor in the electrical system has a built-in resistivity. This means that part of the electrical energy that it carries is dissipated as heat and is lost as useful energy. For a given conductor diameter, those energy losses can be reduced by choosing material with a high electrical conductivity. The electrical conductivity of copper is second only to silver and is 65% better than aluminium. Energy losses can be further reduced by increasing the conductor diameter. The energy savings that result from increasing the conductor diameter lead, in the vast majority of cases, to a reduction in the life cycle cost of the system.

The wires and cables market in India has come a long way, from being a small industry to a very large one, over the past decade. The industry is mostly volume driven, although it comes with a lot of technical and quality nuances. Over the last 20 years, the industry has shifted from being an unorganised sector to an organised one, although 35 per cent of the industry continues to be a part of the unorganised sector. Smart wiring is a structured way of pre-wiring dwelling units; it helps deploy and manage delivery of low voltage systems and control services, and provides a connected environment effectively and efficiently. The need for smart wiring concept arises from the demand for home technology, which shows no sign of declining despite a challenging housing market. Installed infrastructure like high-speed wiring, and the adoption of broadband enable the growth of wholehome networks for digital media as well as data. The smart wiring system can be divided

Fiber Optics: Cloud Computing to boost segment

Given the rate at which cloud computing has grown over the past few years, it is apparent that servers will need ways to transmit data much faster than what they have been using so far. This need for higher bandwidth is key to the growth of the global fiber optic connectors market, as next-gen data networks are poised to be fully ready for fiber optics integration. The global fiber optic connectors market is further propelled by the advances in technology that it has been witnessing recently. The application areas of fiber optics are increasing as well. Optical fibers are now in high demand in defence and aerospace industries for the same reason why telecom companies are using them: larger bandwidths.

Fiber optics is fast becoming a mainstay in most networking industries where rapid transmission of data is a necessity. They transmit far more data than conventional copper wires and additionally possess the massive advantage of being immune to electromagnetic interference. Fiber optic connectors are mechanical links between two optical fibers. They

attributes by reinforcing innovations, competitive prices, premium quality and living with our vision “Tomorrow”s progress today. We believe in Realiability, Respect, Reputation and Repeat business across all manufacturing facilities. In 2007-2008 Apar established a strong foundation for Automotive Lubricants under a Licence Agreement with eni S.P.A, Italy for manufacturing high-end automotive and specialty lubricants under the reputed “eni” brand in India. We have our global presence in over 100 countries of the world. Apar is the fourth largest Transformer Oil manufacturers in the World, Third Largest in the world for manufacture of Aluminium and Alloy Conductor. Our Power Cable Division is also doing very well and is able to offer entire range of Cables ie., Power and Telecommunication. Apar has full range of cables like Rubber/Elastomeric, Optic Fibre, Specialty Cables, Under Water Cables, Cables for Renewable Energies plant like Solar and Wind Energy. We are proud to say that within a span of very short period Apar”s cable division was able to offer Innovative Cable Solutions. Apar’s export division for Cable is also doing very well exporting about 50% of the products produced. Apar has diversified its activities and set up state of the art high Technology Electron Beam Irradiation facility at Khatalwada, Gujrat for cross linking of for cross linking of insulation and innersheath polymers with 1.5 MeV 3.0 MeV along with most modern handling system for Irradiation of various types of Electrical and Automotive Cables, PE sheets, Polymeric Tubes and Pipes, Heat Shrink Products, Gems and Diamonds, Medical Products sterlisation and reprocessing of PTFE scrap etc. Apar is also one of the preferred suppliers for supply of Solar and Wind Mill Plants cables. Apar’s market share is more than 50% for such types of cables.

According to you, which of the segment has more growth potential in the coming 3 or 4 years? Since economy is growing and we hope that there would be improvement in all segments. Government has given thrust on improvement in the Power Sector and have introduced new schemes also government has given thrust on Renewable Energy Plants ie., Solar and Wind Energy. We expect there would be high growth for our Aluminium/Alloy Conductor Division and also in Cables particularly in Solar and Wind Energy. Fibre Optic Cables would also get good boost because government is improving the broadband communication system. It is observed that pace of development in the power sector generation is very slow because of longer gestation period. Lot of disputes at the time of land acquisition and no proper coal linkages to the Power Plants. Hence, there are no new power generation as envisaged and power industry is suffering because of lack of requirement.

What are the major challenges in the power industry in India? How do you overcome with these challenges? Power Industry is doing well in India and condition of industry can improve further provided discoms are able to make payment in time. They don’t make payment due to which financial position of various companies in the Power sector are suffering. In addition to this discoms are not able to spend money for renovation of their projects which are very old. Hence, generation of demand is not existing and Power Industry in India is suffering.

opment in the power sector generation is very slow because of longer gestation period. Lot of disputes at the time of land acquisition and no proper coal linkages to the Power Plants. Hence, there are no new power generation as envisaged and power industry is suffering because of lack of requirement. In anticipation that huge power generation would improve year by year but it has been noticed that power generation is not improved as envisaged. In anticipation power industry improved their manufacturing capacity and hence they are suffering because of non utilization of their manufacturing capacity. Another typical challenge is that there are no standardization of specification among the electricity boards/discoms due to which electrical industry is facing challenges to manufacture material against different specifications. Hence, cost of electrical goods produced with different construction is very high. Foreign suppliers are very much active in the Power Industry due to which Indian Power industries are suffering badly because of heavy competition from the foreign suppliers. On the Export front, Indian manufacturers are losing market share and the exports are dipping due to stiff competition. The Indian Power Industry is not able to compete effectively in the world market because of strong support of some of the countries like China, Middle East in terms of export subsidy, subsidy on raw materials, subsidy on social security and long term line of credit at lower rates of interest. We are overcoming these challenges because at present we are not dependent on Power distribution companies/discoms to avoid problem in circulation of funds. We are also making lot of efforts in diversification so that new products are developed for the markets where competition is very less and good market price is also available. We have developed products for the Solar industry like Anti Rodent Solar Cables, Electron Beam Irradited Cables and also Flexible ||www.electricalmirror.in||

Aluminium conductor. We have also developed Wind Energy Cables upto 33 kv in Elastomeric/Rubber construction for various international buyers. In addition to the above we have also introduced improvement of products quality and cost cutting so that we are able to compete in the global market ie., to keep a tap on the export market. Government, has also considered various measure to improve the export market.

What are the products you are going to showcase in Elecrama2016? Is there any plan to unveil any new product in this event? All products like ACSR / Alloy Conductors, Speciality Oils and Power Cables, Control Cables, Fibre Optic Cables, Medium Voltage Covered Conductor, Speciality cables for Solar and Wind Energy Plants and also E Beam Irradiation products.

What are the opportunities you are looking forward from this event?

ELECRAMA gives opportunity to the Indian Power Industry to showcase their products to Indian as well as the overseas buyers. This is a World Electricity Forum where many companies show case their products or developments which has taken place. People from all the over world visit this show. The focus areas currently identified are in the areas of energy generation such as clean coal and renewable energy efficiency, smart grid and smart cities.

QUALITY, SAFETY AND LONGER SPAN OF LIFE OF WIRES & CABLES.

lectrical Wire and cables have become part of our daily life so need arises for Good Quality of Wires & Cables which is safe and have longer span of life. You may talk about lighting in your house, your refrigerator, your household electrical appliances everything revolves around the Wires and cables because everything requires Power to run and Wire & Cables is the only way to power them. Everyday our life is improving because of level of income is increasing and according to our level of income we require more comforts and more electrical house hold equipments. It shows that continuously we have been increasing the load on our Wires and Cables. It has been noticed that many a times contractors and even user does not know about the Quality of Wires and they have been using it in their household or buildings due to which they find problems that wires are not able to withstand higher current and get softened. Secondly, many a times user try to purchase wires or cables which is cheaper to save money but ultimately they put themselves into trouble when load increases.

HOUSEHOLD AND COMMERCIAL BUILDING Many a times we hear that there are fires in Residential and Commercial buildings it is just because cables & wires are not able to withstand the load and get melted and short circuit conditions are there hence they are putting life into danger. Now a days Fire Departments are making stringent rules so that safety of the people can be maintained. Hence, it is making people aware of the safe wires and cables which can reduce chances of fire hazards. This is very very important that we may take care of the human life which is very precious. We find that projects like Malls, Theaters, Railways Stations, Airports where general public visits regularly and they need to be 96

ELECTRICAL MIR ROR

protected from such Fire Hazards. This is possible only when we use good quality of Wires and Cables in such projects. Wire and Cables used in such projects should be Halogen free, flame retardant and meet the requirements of keeping the life of human as safe as possible. It is also necessary that life of the cable should be longer so that it does not require change of wires & Cables very frequently which will cost us cost of cable and rewiring charges etc. Wire and Cable used should be such the it does not catch fire, halogen free, flame retardant, having longer life and over and above Wires and Cables should be able to carry future load on the cable. We should be very particular in area where temperature goes upto 50 Deg. C.

SOLUTIONS Our R&D Department has developed Wires and Cables which can meet the stringent requirement as explained above. APAR’s has come out with a

developed specially formulated PVC so that it meets the requirement of Halogen, Smoke, Fire Retardant and having longer life.

WE AT APAR We in Apar is constantly working with their R&D team to bring solution the problems we have discussed. APAR has seen so many accidents and it was observed that we may bring a solution to the problem so that human lives are safe and solution should not be costly ie., solutions should be cost effective also We have installed state of the art Electron Beam Accelerators (1.5 MeV and 3 MeV) have been installed as one of the greenfield project in Western India at Khatalwada Gujarat about 20 kms from VAPI. At Apar we have complete handling system to Irradiate the Wires, Cables and various other materials to improve their properties. Details of some of the improvements are given below in the Table:

solution that the Wires and Cables are able to withstand higher temperature, Halogen Free, Carry higher current and PVC does not melt and flame retardant. APAR’s Wires & Cable will give full protection to various commercial and residential projects where general public visits regularly and in large numbers. It is added that even if there is any fire it will not propogate and keep the buildings safe and fire proof. It has been noticed that gases eminating from the Wires & Cables are often suffocating the human life and Wires & Cables we developed reduces halogenic gases and making the life of the human safe. Our R&D Lab has

In nutshell let me conclude this that Wires and Cables with E Beam Irradiation are:• Higher Temperature withstanding capacity utpo 105 Deg. C • High current carrying capacity • Prevent short circuit • Heat and Melt resistant • Passes the Hot Deformation Test • Reduced smoke. • Reduced Toxity • Longer operation life span.

the highest potential for LED Street lighting in India. The below sections details out the various routes in which Street Lighting is done in India.

3. City Roads Street Lighting in India – the background: The City / Urban Roads lighting is the main responsibility of the local government body – the Municipal Corporations or Urban Local Bodies (ULB’s). There are 269 such bodies in India. The Electricity Department in most of these bodies undertakes the Lighting responsibility. Earlier (5 years back), the MC/ULB’s used to undertake the complete ||www.electricalmirror.in||

responsibility of setting up Street lighting and taking care of its maintenance in India. The local electricity utility (mainly government

couldn’t be done. Thus, this increased the risk associated with the project, particularly as the payments were made contingent to the minimum savings achieved. Then, came the new initiative by the UPA 2 Government to take this to a new level through an entity called as EESL.

owned) used to subsidize power supply to these bodies. As the power consumption grew for Public Lighting, there was an increasing awareness on the electricity efficiency side of the business and Public Lighting was considered as one major area for immediate action. As per the 18th Electric Power Survey of CEA, the estimated energy consumption in Indian public lighting sector with 2009-10 as the base year is about 8478 million KWh in 2012-13. The sector will grow at a CAGR of 7% during the XII and XIII plan periods. The chart below indicates this trend: Seeing this growing trend, the Ministry of Power, through its energy efficiency body – Bureau of Energy Efficiency (BEE) started looking at this sector in detail and helped the MC’s and ULB’s to improve the energy efficiency here. During the 11th five-year plan(200712), through detailed energy audits, BEE supported DPR development for 134 municipalities across the country. In addition, the BEE programme helped enhance the understanding of the opportunity among various Municipal Administrations. This enabled MCs to use DPRs and implement projects on ESCO (Energy Services Company) mode at no budgeted investment. The ||www.electricalmirror.in||

various reasons given below and the MC’s & ULB’s were unable to get good ESCO’s to partner with them. The key reasons for this failure at that time were as follows: • Conditions listed out in the tenders issued were not conducive for a private investor / ESCO to participate in this, these were: • One of the key requirements of the bid was a minimum guarantee of energy and cost savings. While guaranteed or shared saving model is at the heart of ESCO business, its application requires certain pre-conditions to be fully met. • The primary need was to have a baseline that was close to actual reality; adequate data on consumption patterns that could normalize the seasonal and other variations; and the equipment installed meet the required standards. These issues were not met in most tenders, and it was extremely difficult to deliver a guaranteed savings unless the pre-project baselines are reset. • The practical situation in most municipalities is such that none of the three conditions were met nor were the baselines. As a result delivery of minimum savings

The Ministry of Power introduced a new entity in 2012 called as EESL – Energy Efficiency Services Ltd – EESL is promoted by Ministry of Power, Government of India as a Joint Venture company of four Central Power Sector undertakings viz NTPC Ltd, PFC, REC and Power Grid. EESL was set up to create and sustain markets for energy efficiency in the country. EESL works closely with Bureau of Energy Efficiency (BEE) and is leading the market related activities of the National Mission for Enhanced Energy Efficiency (NMEEE), one of the 8 national missions under Prime Minister’s National Action Plan on Climate Change. EESL seeks to unlock market for energy efficiency in India estimated of Rs. 74,000 crores resulting of about 15% of present consumption. It seeks to create market access, particularly in the public facilities like municipalities, building, agriculture, industry etc., implement innovative business models, handhold private sector Energy Service Companies (ESCOs) in an effort to ensure replication. EESL has studied the failures of the past tenders in many states and came up with a much better business model to help MC’s/ULB’s with bettering Street lighting efficiency using LED’s. These include: 1. Payments not linked to energy bill: Payments are based on initially demonstrated and agreed energy performance.

Repayment of Investment: On fixed annuity paid by MC monthly or quarterly. Name & No. of MC

and monitoring the project using its own funds or

for the investments is a little over 7 years.

• Provide transaction support to municipalities to develop and design projects, develop contract documents, provide project management service and undertake monitoring and verification

The other significant highlight that comes out, particularly from the standpoint of aggregation of demand is that there is a potential replacement of ~3.5mn streetlights as shown below:

EESL had done a comprehensive study at a MC/ULB level and it estimates that in 269 ULBs, there is an opportunity of annually reducing the energy consumption by 711 million KWh,

This is as on 2012-13 and for select ULB’s only, and now the estimate for an all India level is close to 300mnstreet lights and our estimate is that around 5.5 to 6 mn street lights will be in the

TRANSFORMERS, STAMPING & LEMINATION

Cautious Optimism in The Transformer Industry in India Now The current state of the industry Transformer Industry is one of the key segments of the ‘Electrical’ capital goods industry. This industry is also considered as the bell weather industry for many other Electrical products markets such as Capacitors, Switchgears and Insulators etc. So, from an Electrical industry perspective, it is very important to assess the state of the Transformer industry for one to get a sense of the overall Electrical Products market. The Transformer industry in India is a highly fragmented industry with over 250+ players and the industry estimates from various bodies and experts put this estimate to be around 300-400 players depending on who is one talking with. From, our research perspective of this industry,

110

ELECTRICAL MIR ROR

we consider over 250+ players to be active in this industry. It is estimated that the industry capacity in India is estimated to be over 1000 GVA. This industry has been under a rough weather over the last 2 years with a demand stagnation in India. This industry is estimated to be stagnating between 250,000 to 280,000 MVA for the last 2 years and recently showing some signs of growth. In terms of sales by products, the Power Transformers in MVA terms is clearly over 70% of this market while Distribution Transformers account for over 30% of the market in MVA terms but could show a reverse trend when we talk in terms of number of Units. The industry is governed by mostly the Oil Filled Transformer industry

|| JANUARY 2016

and Dry Type of transformers (only in DTR space) have not yet gained full acceptance due to their high costs. Copper windings still account for a major portion of the industry, while Aluminum windings are mostly limited to < 250 kVA levels. As a nation our overall transformation norm stood at 7MVA/MW levels in 2008 and the policy makers had a plan to reach the levels of 11MVA/ MW levels in the 12th plan. But, due to various factors and the state of DISCOMS largely, we are still hovering around the 8 to 8.5 MVA/MW levels. Our research on this industry over the years shows that Utilities demand for Transformers is a highly important one and accounts for over 90% of the industry’s output. The remaining

being the Industrial requirement of Transformers for their projects. Over the last 2 years, the lack of new Transmission project orders, poor state of the DISCOMS and the tepid industrial activity had kept the industry in a low performing state with demand stagnation. This also led to an increased price pressure and smaller players losing out closing down operations.

New hope of revival in the Industry The aggressive activities of the NDA 2 Government in the Energy sector and overall positive investment climate has led to most players feeling more hopeful on the industry prospects. Even though the actions have not led to a huge increase in order booking yet but most industry players are seeing signs of revival and expect this to open in the near future. Some key initiatives and actions that have led to this cautious optimism are: • Existing and planned projects and 112

ELECTRICAL MIR ROR

orders from the RE projects in India – Solar Parks and Projects and Wind projects • The opening up of new transmission projects and the de-bottlenecking of old stuck projects has led to order wins by many firms in the recent past for the Power Transformers. • The upcoming new transmission projects and the Green Energy Corridors will see more uptick in the Power Transformer Segment going forward. • The announcement of UDAY and the participation of 15 states already in the program has given many players some hope that the fiscal conditions of DISCOM’s would improve and this would lead to more aggressive DTR purchases in the next few years to reduce the losses. • Even though the Government had announced 2 major schemes of Integrated Power Development Scheme (IPDS for the Urban areas)

|| JANUARY 2016

and Deendayal Upadhyaya Gram Jyoti Yojana (DDUGJY for the Rural areas), nothing of note till now has been seen on ground from these schemes. But now, with UDAY being implemented in many states, this will provide a framework for most utilities to absorb the additional investments in IPDS and DDYGJY programs and implement them on the ground more effectively. • The revival of investment in manufacturing and new CAPEX investments due to ‘Make in India’ has not yet happened but most industry players are cautiously optimistic about the same.

CASE

STUDY of The Month

VARIOUS CASE STUDIES ON OPERATION AND CONTROL SCHEMES FOR GRID SUB-STATION Contdâ&#x20AC;Ś. 1. Introduction: For the last few months, the response of the readers to the case studies on various incidents is in demanding trend. Hence this month we are again choosing the write up on similar kind of studies for developing the synchronisation of practical observation to the theoretical concepts. The analysis of each incident being supported by actual observations had been described during the situation to add awareness amongst the operation, testing and commissioning engineers to know the cause of problems and be helpful for easy rectification of the problems. This can also help to develop economic schemes for the smooth running of the operation and control system in the Grid Sub-Station. 2.1 Unbalance Current in the System: - In one of the 132/33 KV Grid Sub-Station, the current flow on a feeder was found as follows. Rph Current = 0.7A ( Primary value = 140Amp) Yph Current = 0.7A ( Primary value = 140Amp) Bph Current = 0.4A ( Primary value = 80Amp) Neutral Current = Nil

Traction loads were on R Phase and Y phase. So current on these two phases as compared to B Phase became more. For the condition as shown in the figure-1, IR = I1R + I2 IY = I1Y - I2 , IB = I1B IN = IR + IY+ IB = (I1R + I2 + I1Y - I2 + I1B) = (I1R + I1Y + I1B) = The sum of balanced load current on the system = ZERO = Nil. So this can be concluded here that for the case of any load being connected from any two phases cases the addition of current to the system and subtraction of the same in the other phases, for which the net effect remains as the balance load current and under normal condition, the neutral current becomes ZERO. 2.2 Tripping of REMOTE system: For any fault on the local Sub-station, the remote end 132 KV breaker was tripping frequently.

For this condition, the Non-directional E/F element did not actuate. Why and How? Analysis: - For this grid sub station, along with normal 3 Phase load, traction loads were also available.

Analysis:- For this condition, fault on the 33 KV feeder should not be extended to the remote station, because this has proper relay gradation at the local station. But on detail collection of data regarding the relay setting it was found with the following. At Local Station :- 132 KV TFR end

CTR = 150/5 O/C Setting ( PSM= 20 %, TSM=0.5 IDMT) E/F Setting (PSM= 10 %, TSM=0.5 IDMT) At Remote Station: - 132 KV GRID end CTR = 100/1 O/C Setting (PSM= 100 %, TSM=0.1 IDMT) E/F Setting (PSM= 15 %, TSM=0.05 IDMT) Analysis:- For the condition of normal current flow, the current magnitude on the secondary side of the relay can be calculated as follows. Say current of 100 Ampere is For such condition if any fault results in the system, considering of current rise and voltage being zero on the DP relay, this relay actuates and trips the concerned breaker. It may be noted here that this feeder has old English make type RR3V electromagnetic relay. Rectification:- The PT supply to the relay was put into service and after that no such incident was observed. 2.3 Non Tripping of Trip Coil for Measured value of Voltage:- While checking the TCS ( Trip Circuit Supervision), voltage of 236Volt was measured at the wire coming from the control room used for tripping of the breaker, disconnecting the wire from the circuit. But by connecting this wire

to the tripping terminal, the breaker did not trip. WHY?

||www.electricalmirror.in||

CASE

STUDY of The Month

By disconnecting the TB as shown when voltage is measured by the voltmeter, the voltage coil resistance ( HIGH OHMIC VALUE) comes in series to the circuit, for which the current drawal from the circuit becomes very small ( range may be in milli ampere). Now the voltage drop across the TSR being very small got neglected and voltage measured by the meter becomes of 236 Volt. But while connecting this wire to the terminal, the TSR (Trip Circuit Supervision Relay) resistance and Trip Coil resistance becomes in series. The value of TSR resistance being very high allows the maximum drop across it and did not cause the trip of the Breaker. 2.4. ZERO WATT Reading from Energy Meter - It was observed ZERO

reading by an energy meter on the instant Wattage value for a light loaded line. The values are as follows U1= Voltage of R Phase= 78.5 KV, U2= Voltage of Y Phase= 78.4 KV, U3= Voltage of B Phase= 78.2 KV, I1= Current of R Phase= 16.9 A, I2= Current of Y Phase= 16.5 A, I3= Current of B Phase= 16.4 A, PF= 0.99, L= Instant KW Loading = 0 ( Nil). Why? Analysis: For the correct connection of Energy meter, the reading of each wattmeter shall be ( VxI xCos angle between them). Here PF is 0.99. Hence it is understood that the phase angle is ZERO or very small). By calculation the wattmeter reading should have come as ( 78.5x16.9x 0.99 +78.4x16.5x 0.99 +78.4x16.4x 0.99) = 1313.38+1280.66+1272.9= 3866.94 = 3.866 Mwatt. But the reading is coming as ZERO. This situation may result for the 116

condition of wrong sequence of the VOLTAGE or CURRENT to the energy meter. For the figure shown Fig-4, the voltage and current vectors have been considered in wrong sequence. In one figure the voltage vectors have been wrong sequenced and in other current vectors have been changed. For both the case considering the phase angle being very small, the total reading could be as follows. (78.5x16.9x cos ( 120 deg) + +78.4x16.5x 0.99 +78.4x16.4x Cos (240 deg) = -663.32+1280.66 -636.45 = 19.113 = Considered Small and taken as ZERO. Verification:- On physical verification it was found with the WRONG SEQUENCE OF THE VOLTAGE supply to the meters. The correct sequence was changed and put into the circuit. 2.5. Abnormal Reading of Energy Meter:- A 220 KV line feeder was idle charged from one Grid Substation. It was observed with the considerable MWH recording by R phase coil as compared to other phases. Accordingly the distribution company also charged the billing towards the recording. But there was no advance at the receiving end. Analysis: After such the connection and terminal reading of all the parameters on the energy display were checked and found with some active current on the R phase below the E/F relay setting of the protection scheme, because of which the E/F relay in the scheme is not actuating. However due to this value of current, the coil is recording the active power. It was suspected on the CT and accordingly the testing was done and found in order. Then it was asked for patrolling the line and found with the following

|| JANUARY 2016

problem. The R Phase conductor was having low clearance of 3 ft with an ASH DUMP YARD inside a factory premises. Because of this the current is tracking and resulting certain active current and rise of MWH reading. Necessary action was taken with proper barricade under this conductor and the problem was rectified. 2.6. Frequent tripping Transformer on Differential Relay:- This was observed with tripping of 20 MVA, 132/33 KV Transformer on Differential relay frequently during night time between 11 PM- 5 AM. This incident repeated 他 days continuously.

Actions:i. The said transformer was taken SHUT DOWN for detail testing and results were found in order and no any abnormality was found. ii. The CTs involved to the relay circuitry were checked and found in order. iii. The CT circuitry was also checked and found OK. iv. The current response during online condition was checked and also found in order i.e no such abnormal or un balance currents were observed. v. Finally it was decided to check the

same ON LINE during night time ( between 10 PM-6 AM). vi. Accordingly the tripping wires from the differential relay and E/F relay to master relay were removed. ||www.electricalmirror.in||

vii. The following observed.

readings

were

having Primary terminals as P1 and P2.

a. The spill current on differential relay was found of magnitude 50 mA at around 11.15 PM.

ii. Primary terminal P2 is in directly connected to the Top Cover and P1 was provided with EPOXY CAST insulator between Top cover and conductor. Under working condition the conductor only carries current and insulator as provided between P2 and cover, the cover does not carry any current. ( Refer Fig- current

b. Facility was kept for continuous recording of the spill current and observe with gradual rise of 50mA100mA- 175mA -200mA-250mA and on c. As the pick up setting was with 175 mA, the relay trips but the transformer did not trip due to removal of tri wire to the master relay. d. Similar rise of current was observed for all other cores. e. The individual value of both side (132Kv and 33 Kv ) on each phase were checked. f.

The current on the 33 KV side were obtained all equal value of 150 mA on each phase.

g. The current on 132 KV side were also measured and found with 100 mA on R phase, 150 mA on Y and B Phase. h. The reading on R phase started reducing gradually in due coarse of time.

iii. As the Sub-station is near to the Sea shore, during night of those days the moist air in touch with dirt and dust being depositing on the epoxy insulator was causing flow of the parallel path of primary current. Hence the current for participation of the ratio gets decrease and accordingly the secondary current also becomes different, resulting the flow of spill current on the differential relay for tripping of the relay. 2.7. Tripping of Transformer on REF relay:- One of the ICT was tripped on REF protection for the following condition. This ICT was idle charged from 220 KV side

i. The observations on the currents to other phases were also taken with removal of tripping wire from the master relay.

And 400 KV feeders were under shut down condition. Fault resulted on the B bus side Tie feeder CTs. ( 400 KV Source was not available)

j. To the case astonishment, the similar behavior started with other two phases on secondary side of the CTs.

Analysis:- The Tie was under closed condition and occurrence of BUS fault causes tripping BUS Bar Protection relay and successfully clears the fault. Such action of BB relay was normal. But simultaneous tripping of REF relay of the ICT was abnormal.

Decision: Because of this nature of abnormal current flow and to avoid frequent tripping of the transformer, all the three CTs were replaced on the 132 KV side by new one. Then this problem was rectified. Analysis: The changed CTs were physically investigated and found with the following structures. i. These CTs were of LIVE TANK CTs 118

ELECTRICAL MIR ROR

The REF relay used in the system is of ABB make and setting of the relay is on the basis of Voltage development across the relay during fault condition. In practice for the condition of internal fault, the current becoming very high, develops the voltage above than that of the setting and trips the transformer.

|| JANUARY 2016

In this condition the fault current as recorded by the relay becomes 9KA on the 220 KV side. The calculation of Vs= Voltage across the REF relay = If x ( Rct + 2 x RL) /N = 9000x ( 3 +2x1) / 1000 = 45 Volt . But the relay was set with value of 40 Volt. So the REF relay tripped. Rectification :- The setting was changed to the next higher value of 50 Volt. The problem was solved and tripping did not occur. 2.8. Tripping of Transformer on Auxiliary Relays:- Tripping of 40 MVA, 220/33 KV Power transformer, on Mechanical Relay Protection Relays ( WTI, OTI, BUCHOLZ, PRV etc..) for the condition of heavy fault on the 33 KV feeders going out from the 33 KV Bus of the Sub-Station.

Observation on Checking :1. The detail circuit of the Mechanical Protection relays related to the DC leakage was checked but found with no any discrepancies. Moreover this kind of apprehension could be overruled because if it would have the reason, then all the time during the fluctuation/ Change of DC supply this could have been occurred. But such occurrence of the incident was only resulting during the time of Close in fault on the 33 KV feeders. 2. This was found with use of ARMOURED CABLE on the Protection Control circuit from MK (Marshall Kiosk) to Relay Panel in the Control Room. 3. This cable was in damaged condition and black insulation cover over the armouring portion being damaged was kept in touch to the LT Neutral conductor. Analysis:- In fact the occurrence of the fault, specifically on the out going feeder, has the source of its origin is the winding of the transformer. LT side fault results the current flow path through ||www.electricalmirror.in||

the LT neutral conductor buried to the sub-station earth mat. During close fault in the system, the fault current becoming very high results rise of potential on the ground conductor. In this situation, the ARMOURING PART being in touch to the LT Neutral conductor results momentary rise of potential on it. At the same time the reflection of this rising voltage on the return wires in the cable, meant for mechanical protective relays, causes the unwanted voltage appearance on the relay and tripping of the scheme.

Actions Taken:1. The armoured cable was replaced by normal cable and re-routed away

||www.electricalmirror.in||

from the LT neutral conductor of the transformer. 2. The LT neutral conductor buried to earth was checked and strengthens by use of another connection to the Sub-Station Earth mat. 3. Similarly the earthing connections for HT Neutral were checked and strengthen. 4. Then

RENEWABLE ENERGY

Emerging Renewable Energy Trends in India

hile 2014 undoubtedly remained a challenging time for the solar industry, it did mark an inflection point in the market’s development. Volume demand grew at a double-digit pace again, largely thanks to policy in China and Japan. Yet conditions remained extremely tough for suppliers. The supplier base consolidated further though mergers, acquisitions and bankruptcies, as companies struggled with debt-laden balance sheets and a rapid shift in their customer base away from their traditional markets. All of the signs point to a strengthening recovery of the solar industry in 2015 even if the recovery itself remains incredibly fragile. Policy support will continue to be key, and demand still will be highly concentrated in a handful of countries, presenting significant risk. Nonetheless, the rapid price declines seen by the industry has opened up solar to an enormous number of countries around the world, with several new business models emerging in the post-FiT world. More than 40 countries globally will install at least 100

120

ELECTRICAL MIR ROR

megawatts of new solar PV capacity in 2015, signalling the true entry of solar into traditional energy generation. Top future trends for 2016: 1. Global solar PV demand to grow by up to 25 percent in 2015 2. CPV to see accelerated growth in 2015 3. Distributed PV in China to fall behind expectations, but continues to grow 4. Grid-connected PV energy storage installations to triple in 2015 5. Emerging markets mature – Chile follows South Africa to reach 1 GW of installed PV capacity 6. Monocrystalline technology to increase market share in 2015 7. Systems up to 100 kilowatts to account for 30 percent of global installations in 2015 8. Q2 halt to UK utility-scale PV triggers new wave of consolidation among European EPCs 9. Three -phase string inverters to

|| JANUARY 2016

account for one-third of global solar inverter revenue in 2015 10. California in 2015 will become global leader in solar power penetration Solar energy: The solar industry in 2014 was characterized by double digit installation growth, moderate revenue expansion, a return to almost respectable margins, the restarting of capital investment and further M&A activity and consolidation in the supplier base. In many ways, 2015 will be very similar, we expect, with this fragile industry entering a healthier phase. Installation demand will grow at a double-digit rate of 16 to 25 percent and installations in the range of 53 to 57 GW. The drivers of growth will remain largely unchanged from 2014. Geographically, the largest markets again will be China, Japan and the United States, while the largest contributors in terms of absolute growth will be China, the U.S. and India. The underlying driver of growth will be the ongoing cost reduction of solar. The continued ||www.electricalmirror.in||

focus among countries on diversifying their energy mix away from imported oil and fossil fuels also will remain the same. It might be noted that the Narendra Modi government raised India’s solar capacity goal to 100,000 megawatts by 2022. The target is an ambitious 20 times current production. If India can meet it, it will become one of the biggest solar powerhouses in the world. India’s Prime Minister Narendra Modi made a big push for renewable energy by raising the target twice. And that is taking this industry to another level. While in 2014, his government upped the 2022 target of the national solar mission to 100 gigawatts, from the earlier 20 GW. And at the Paris climate summit in December, he said that India will produce 175 GW from non-fossil sources 122

ELECTRICAL MIR ROR

by 2022. In eight years after that, 40 per cent of the nation’s electricity will come from renewable energy. Such ambitious targets have spurred big-ticket investments, and a bunch of companies have emerged to take advantage of the opportunity, which includes getting subsidies over a period of time by the government to encourage more companies to set up plants for solar and other renewable energy. India will need to add 15 GW of capacity each year until 2022 to meet the goal set by the government. India’s current installed capacity is 2,900 MW. No country has ever managed to grow like Modi’ s government wants it to. China, the largest producer of solar energy, has a capacity of 40 GW.

|| JANUARY 2016

Germany, which leads in renewable energy in Europe, has lower installed capacity. For now, the sector is growing fast and that pace is expected to accelerate in 2016, assuming that the broader macro environment does not worsen significantly. However a major challenge will be on selling solar power to state-owned distribution companies that are heavily indebted in several states such as Delhi, Tamil Nadu, Uttar Pradesh and Bihar. Gujarat, where Modi had launched a solar mission when he was chief minister, is now a power-surplus state, so does not need that much of solar power. Second, a bidding war might force renewable power producers to bid for lower tariffs that might hurt profits. The companies will ||www.electricalmirror.in||

RENEWABLE ENERGY be helped by the decreasing costs of solar and wind power, which can now rival that produced by new coal plants. But that said, the year ahead promises to bring in a lot more addition in solar capacity, and might see even lower costs of production at a wider scale. Investors would be watching to see if the electricity can be profitably sold. While addressing the Indian Science Congress in Mysuru, Mr. Modi said that innovation must not be just the goal of our science; it must also drive the scientific process to make it easier to do scientific research in India. He added that we should work for India to stand out in global science. On the context of renewable energy, he said, there is an urgent need innovation to make renewable energy much cheaper, more reliable and easier to connect to

transmission grids.

According to the PM, innovation is important not just for combating climate change, but also for climate justice, we need research and innovation to make clean energy technology available, accessible and affordable for all. We must also address the rising chal-

said. While reiterating that cities are the major engines of economic growth, employment opportunities and prosperity, he said, â&#x20AC;&#x153;We must develop better scientific tools to improve city planning with sensitivity to local ecology and heritage. Cities account for more than two-thirds of global energy demand and result in up to 80% of global greenhouse gas emission, he pointed out the need to develop better scientific tools to improve city planning with sensitivity to local ecology and heritage. Expressing concern over solid waste management, he indicated that we have to find affordable and practical solutions for solid waste management. A sustainable future for this planet will depend not only on what we do on land, but also on how economies treat their oceans. ||www.electricalmirror.in||

Competition from China There are a lot of cheap and low-quality products coming in from China that erodes consumer confidence in solar, because these systems are known to fail. However, the stiff and breakneck competition from China is always looming large over Indian confidence. During the Asia-Pacific Economic Cooperation conference in Beijing in November 2014 that drew 21 world leaders to the city, haze was temporarily absent from the Chinese capital city for about 10 days. The Chinese invented a new word to describe the blue sky during this period—APEC blue, for the short-term pollution-free status of the city’s heavens as a result of temporary administrative measures, including the shutdown of heavily polluting factories and restriction on the use of automobiles. Such measures had been in place before, enacted during the Beijing Olympics in 2008.

President Xi Jinping has expressed his keen wish to keep the skies blue over Beijing even when there are no international conferences or events, demonstrating the importance of the using carbon-free technologies in China. However, China which is the world’s biggest clean energy investor, plans to increase wind and solar power capacity by more than 21 percent next year as it works to reduce greenhouse gas emissions by cutting its reliance on coal. According to a power ministry official, strengthening transmission lines and improving grid infrastructure will also be crucial. Costs are pushed up because providing services to small rural projects is currently expensive and lack of quality control on solar products tends to cause major setbacks. For once, though, India’s massive population may actually be an advantage in bringing costs down. The nation is targeting at least 20 GW of new wind power installations and 15 GW of additional solar PV capacity next year, the National Energy Administration said in a statement recently. China has pledged to peak carbon emissions around 2030, by which time it aims to derive 20 percent of the energy it uses from clean sources. China will also stop approving new coal mines in the next three years. Nevertheless, India is expected to lag behind its Asian counterpart and is doing it bit to catch in the Asian dominance over the Solar power play!
