Speaking on the occasion, Hon’ble Railways Minister, Shri Suresh Prabhu, mentioned “Distributed generation is becoming a necessity and hopefully very soon it will become a reality. India needs to bring in distributed generation of electricity to meet its electrical energy demands. These generations are based on the technologies, mainly renewable, including but not limited to wind turbines, photovoltaic cells, geothermal energy and micro hydro power plants. Through this we can reach those villages which are in remote areas where our transmission lines cannot reach. Thus the role of utility has to go under sea change in years to come. “ He further added “The climate change has itself put the focus on the necessity of renewable energy and we are trying to use this opportunity to help the transition to a cleaner and greener world. Our Prime Minister has come with new idea of Global Solar Alliance and it aims for around 125 solar rich countries to collaborate and together chase this sustainable energy source. Nobody has thought that India would think of

achieving 100,000 MW by 2022. This is a giant step and India will become the biggest producer of solar power in the world. I found the Renewable Pavilion at the exhibition remarkable. Several solutions presented here will support the Prime Minister’s vision of ‘Power to All’. ELECRAMA as a platform encourages companies to be competitive and bring out quality solutions that will enable the country’s growth and will also emphasize on brand India.”

Speaking at the inauguration, Mr Phillippe Joubert, Executive Chair- Global Electricity Initiative, World Energy Council, UK said “The World Utility Summit is a very important and timely event.

Innovation day- Engineer Infinite - ELECRAMA 2016 As a part of innovation day, EI16 6KRUW IRUP RI (QJLQHHU ,QÀQLWH 2016) was the Student Project Competition running concurrently with ELECRAMA-2016 exhibition this competition was an opportunity to the students of engineering (Diploma, UG, PG and Research Scholars) to leverage their theoretical knowledge and creativity to address diverse real life issues that need attention, in the electrical energy sector. EI16 invited project ideas from all branches of Engineering & Technology. Project ideas were welcomed from Students of Diploma, Undergraduate, Post Graduate and PhD Scholars of these branches. The critical requirement of the project idea was that these project ideas must pertain to Electrical energy sector and be application focused rather than product focused. 7KH HWKRV RI ´(QJLQHHU ,QÀQLWHµ LV the limitless possibilities that present themselves in the Electrical Energy sector, especially in India. It wakes the young students in this sector, up to the challenges faced and therefore to the countless ways in which these challenges can be met. The aim of the competition was to encourage students to apply their knowledge and skills and present practical solutions to some problems, related to electrical energy sector. The participants were required to build and demonstrate a working model or build and display a simulated

Karnataka Energy focus Karnataka has always given a high priority to the development of the power sector. All segments of the electricity supply chain: generation, transmission and distribution are important and require attention. Addl Chief Secretary (Energy), Government of Karnataka, Mr P Ravikumar shared his views on ELECRAMA-2016 and the challenges the government needs to meet in the power sector. Mr P Ravikumar graced ELECRAMA-2016 with this presence. Of the various observations made at the event, he noted that the exhibition is of great importance as the power industry needs to upgrade its technology. He averred, “In India, more than 90% of the utility business is in the government sector and this sector is in need of a technology upgradation. ELECRAMA is a good forum for this, as this year the review of all the states was done in Bengaluru at ELECRAMA-2016. Partaking in the seminar has been an eye-opener to all the states and state utilities. Furthermore, it is a brilliant venue for seeing the latest technologies under one roof.” Elaborating on the need for technology upgradation, especially in Karnataka, Addl Chief Secretary (Energy) Mr Ravikumar stated, “Karnataka is one of the pioneers for electricity in India, and our T&D infrastructure is about 50–60 years old. Hence, there is a major need for an overhaul in the T&D power structure.” Another challenge the state is facing is with the strengthening of the grid for renewable energy. “One of the main challenges being faced is trying to integrate the ever growing renewables into the electrical power systems. For this, we have to strengthen the grid and increase generation capacities to have grid integration. And this is where ELECRAMA is useful to us as partaking in it we have access to better technology and innovation across the industry under one roof.” PRGHO XVLQJ VSHFLÀHG WHFKQLFDO VRIWZDUH The projects were encouraged to highlight their relevance to focus areas of initiatives by the Government of India and leverage current trends of technology, such as: Make in India, Digital India, Smart Cities, and Internet of things The emphasis was more on application of technology for a solution to the society rather than just developing a product from a technological advancement/ concept. For example, electrical vehicles are available in the market already in the individual space, and hence the projects may now focus on mass transport using electrical mobility. Similarly, UAV as a product is almost available as commercial projects, but the projects must look at applying them

The new Tariff Policy tightens the discretion currently allowed to regulators while setting power

tariffs and makes a strong pitch for the promotion of clean energy. New tariff policy will also support Swachh Bharat programme, better regulations and encourage faster roll out of investments in the power sector. The Electricity Act 2003, requires the Central Electricity Regulatory Commission (CERC) and State Electricity Regulatory Commissions (SERCs) shall necessarily be guided by the tariff policy in discharging their functions including framing the regulations under section 61 of the Act. The new tariff policy tightens the norms followed by electricity regulators for setting terms and conditions for determination of tariffs. After the amendments, it would be binding on the regulators to take decisions as per the new tariff policy. The policy has allows increase in fuel cost on account of import to be included in the tariff structure. In case of reduced quantity of coal supplied by Coal Companies, vis-a-vis the

assured quantity of 85 per cent, the higher cost of imported or market based e-auction coal for making up the shortfall, shall be considered for being made a pass through by the regulators on a case-to case basis, to the extent of shortfall, according to an amendment to the policy.

clean energy, and have a challenge to add 1.75 Lakh MW of renewable energy, GOI bringing certain more elements in tariff policy which will promote renewable energy. It also includes the elements, which will promote Swachh Bharat Abhiyan and help waste to energy, prosper in India. Under the policy, the power plants will have to use processed municipal waste water available in their vicinity (in 100 km radius). It will allow distribution companies to buy any amount of power produced from the waste. The new policy UHÁHFW D FRQFHUQ WR HQYLURQPHQW and encourage renewable energy. It will also help India’s energy security by planning in advance for the requirements for tomorrow. Several unique aspects which have not been touched in the past are being brought out in this policy. The new tariff policy will give a big push to electricity generated from renewable energy sources and address concerns related to the environment. The government in new Tariff Policy increases the Renewable Purchase Obligation (RPO) to 8% for solar energy by March 2022. Distribution Companies are mandated to purchase a certain amount of their energy from renewable sources under the RPO. Then, the amendment on having eight per cent of the total electricity consumption from solar energy by March 2022 will remain a mere goal unless it is enforced by the States. While the existing Electricity Act too mandates renewable energy purchase obligations (RPOs), it is up to the respective SERCs to decide on the quantum and also whether or not they should be legally binding. Similarly, implementation of periodic tariff revisions as mentioned under the new Tariff Policy is dependent on SERCs introducing orders to such effect. Raising the RPO is a necessity, and the single most important regulatory and policy mechanism of government of India to drive solar. Under another part of the policy, new coal or lignite-based thermal plants will also have to establish, procure or purchase renewable capacity as part of the Renewable

March 2016

Generation Obligation (RGO). For the power sector as a whole, the new tariff revision aims to help the government’s Ujwal Discom Assurance Yojana (UDAY), a major upheaval of policy around the country’s heavily debt-laden Discoms. Although UDAY is not mandatory, the majority of states have signed up to the scheme since it was announced. The new tariff policy permitting power companies to pass-through changes in domestic duties, cess and taxes to customers through tariff hikes. In the past, the CERC has held the view that changes in such costs come under ‘changes in law’ and can therefore be allowed to be recovered through tariff hikes but many SERCs have not followed this approach for their respective States, The policy is making an attempt at giving guidance on this. The new power Tariff Policy incorporates changes that would well for the power sector in the long run. While some are intended at improving power supply, others aim at helping power companies recover costs. Then, there are amendments that are targeted at promoting renewable energy. But, while the changes are positive, they are not legally binding as the policy serves largely as a guiding force. Moreover, the actual implementation has to be undertaken by the State governments and the respective State electricity regulatory commissions (SERCs). Electricity for all practical purposes is a State subject. The entire success depends on the extent to which the State governments adopt the changes and follow them. In fact, some amendments such as those relating to competitive bidding for inter-State transmission projects and renewable energy purchase obligations (RPOs) are not completely new. The implementation record on these has however been patchy. The provision in the new Tariff Policy on procurement of power from smaller plants that use poorquality coal (coal rejects generated from washeries) should aid power supply in the areas located close to the mines. Allowing private power producers to expand their capacity

by up to 100 per cent at their existing sites too is a good move. This should help them better utilise the available land and do away with acquiring additional land, to a certain extent.

Improving competition across categories of power projects Tariff-based competitive bidding for transmission projects was introduced a few years ago, some projects have continued to stay outside this mechanism. Under the existing rules, the Centre can allot projects which are technologically complex or require urgent implementation to Power Grid Corporation of India, the country’s principal power transmission company. The amendments to the new Policy now make competitive bidding compulsory even for the central public sector projects. However, coal washery rejects based projects have been exempted from such competitive bidding process until the Government of India decides to introduce competitive bidding process for such projects. In addition, as per the amendments to the Policy, State Government owned generation and transmission companies shall continue to operate power projects based on ‘regulated cost plus tariff regime’ as per Section 62 of the Electricity Act, 2003 for sale or transmission of power within that particular state. The amendments to the Policy also provide that state transmission utilities must endeavour implement larger projects on the basis of competitive bidding. The amendment in the new Tariff Policy is on similar lines. According to it, tariff-based competitive bidding can be done away with in case of exigencies. The new policy therefore has not been able to make the process completely competitive.

Promotion of renewable sources of energy Promotion of renewable sources of energy has been expressly provided as an objective of the Policy. Also, the term ‘non-conventional energy’ has been replaced with ‘renewable energy’. The Renewable Purchase Obligations will be updated on longterm basis by the Ministry of Power, in

The State Electricity Regulatory Commissions will prescribe minimum percentages of purchase of solar energy till generated solar power reaches at least 8% in total energy terms. Tariffs will be determined on ‘cost plus basis’, for the procurement of power from all waste-to-energy plants. A framework for technology based 5HQHZDEOH (QHUJ\ &HUWLÀFDWHV (REC) and a suitable ‘REC Multiplier’ to differentiate between technologies shall be adopted. A separate bid based tariff framework for generation of renewable energy, imposing progressively heavier charges towards the end of the term, will be introduced.

tarting at the end of last century the worldwide interest in renewable energy was encouraging WKH 39 LQGXVWU\ WR JURZ VLJQLĂ&#x20AC;FDQWO\ and this growth around the world was irresistible. At that time the construction of PV systems was an expensive and long term investment and the investors did not know how to estimate the quality of modules, and customers were asking for the expected lifetime of PV modules and PV installations. There was a strong need for a third party assessment of safety and quality.

In 2001 the TUV Rheinland in Germany started testing PV modules and noticed many problems because of the cables, since no dedicated standard tests for these cables existed, the TUV Rheinland created their own standard. This was the birth of 2Pfg 1169:2004 which was based on IEC 60245-4:1994 (Rubber insulated cables â&#x20AC;&#x201C; Rated voltage up to and including 450/750V Part &RUGV DQG Ă H[LEOH FDEOHV

After numerous wiring failures the PV experts recognized, that the requirements of the PV wires were much higher and requirements of the first Pfg 1169:2004 had

been too low. In 2006 a new experts group (German National &RPPLWWHH :RUNLQJ *URXS started to work on a new version of the â&#x20AC;&#x153; Requirements for photovoltaic FDEOHVÂľ ,Q WKH Ă&#x20AC;UVW SDUW RI WKH ZRUN it was a joined group of module and cable experts. The focus was on the period of use of PV wires.

as well as between conductor and earth. These cables are suitable for permanent outdoor use for many years under variable demanding conditions. Relatively stringent requirements are set for these products in line with the expected harsh usage conditions.

In 2011 the German National Committee for PV wires and cables started to work out a revision of VDE-AR-E 2283-4â&#x20AC;&#x153;Requirements for cables for PV systemsâ&#x20AC;?. The target was now toapply this draft as a new work item to CENELEC TC20, The main topics were

To meet the stringent requirements insulation and sheath in modern solar cables consist of cross-linked polymers. Two different processes can be used for cross-linking â&#x20AC;&#x201C; a choice between electron beam cross-linking and chemical crosslinking. Chemical cross-linking is a process that cannot be stopped once it has started. As a result, chemically cross-linked cables suffer from the same phenomenon as old car tyres. They can harden and become porous. By contrast, electron beam cross-linked cables are irradiated with beta rays. This improves the synthetic material. Once the cables have passed the electron beam, the cross-linking process is complete. These cables remain soft and elastic throughout their whole service life. Energy delivered from a Solar PV system is not only dependent on WKH HIĂ&#x20AC;FLHQF\ RI WKH PRGXOH EXW also on other system components like DC Cables, Connectors and Junction Boxes. While designing the solar farm, engineers have to factor the losses from modules to the inverters to calculate the over-all performance ratio of the farm. Low quality solar cables and connectors will lead to small increases in resistance and result in higher losses of energy (I2Rt). The loss of energy already harvested, when calculated over D WZHQW\ Ă&#x20AC;YH \HDU OLIH UHSUHVHQWV D substantial loss and would affect WKH SURĂ&#x20AC;WDELOLW\ RI WKH SURMHFW

To determine the thermal ageing effect, the Arrhenius equation is a simple and accurate formula for the temperature dependence of reaction rates. It is used to model many thermally-induced processes/reactions. A useful generalization supported by the Arrhenius equation is that the reaction rate doubles for every 10 degree Celsius increase in temperature. To determine the long-term temperature stability of an insulation material, the different ageing times corresponding to different temperatures are measured and recorded in the Arrhenius-Diagram (shown below). A straight line is drawn to connect the various recorded points. By extending the straight line until it intersects the 20,000 hours axis, it is possible to determine the service life or the temperature index. A 10Â° C shift in temperature will increase or decrease the process by a factor of two. The temperature index as SHU ,(& GHĂ&#x20AC;QHV WKH DJHLQJ temperature (in Â°C), at which the material still has elongation at break of 50% after 20,000 hours. EN 50618 / TUV rates cable at 120Â°C @ 20000hrs with working temperature of -40Â°C to 90Â°C for solar DC cables resulting in the life expectancy of cables at 90Â°C to be >25 years. A high quality Solar DC Cable is expected to perform for the complete lifetime of the installation ZKLFK LV DERXW WZHQW\ Ă&#x20AC;YH \HDUV The cost of replacing a defective installed cable is very high. The replacement costs increase when factoring in manpower used for removal, reinstallation and testing of the system. In addition, there are losses in power output and revenue generation.

he more attention soars towards the sustainable energy sources, in particular the wind energy. This is considered as the most important and most promising renewable energy sources in terms of development. As wind-power capacity has increased, so it has the need for wind power plants to become more active participants in maintaining the operability and power quality of the power grid.[1] 7KH GHYHORSPHQW RI VXVWDLQDEOH HQHUJ\ IRU HIĂ&#x20AC;FLHQW and clean electric power systems has become a critical research topic worldwide[2-5].Wind turbines are installed in windy sites, which may not have strong grids. There are ORFDO LPSDFWV OLNH YROWDJH Ă XFWXDWLRQV Ă LFNHU DQG UHDFWLYH power absorption when the penetration is low. With high penetration, overall power system gets affected. The Indian Grid code envisages establishing a standard operating practice for wind turbines to minimize these impacts and UHDS PD[LPXP EHQHĂ&#x20AC;WV[6].The objective of this case is to study the impact of voltage dip on grid connected wind cluster power system. This case describes the voltage dip analysis under different abnormal conditions, loading conditions, sudden switching of incoming induction generators to grid system, start up of large numbers of wind turbines, etc. The grid side and wind generator side power quality analysis under said voltage dip condition has been analyzed. There is scope for investigation in grid connected wind cluster under certain conditions such as fault closer to wind turbine and grid side , sudden switching on and off the heavy loading condition, increasing of FXUUHQW GHPDQG E\ IDOOLQJ WKH YROWDJH SURĂ&#x20AC;OH IXOĂ&#x20AC;OOLQJ RI reactive power demand from the utility, etc.

The static requirements discuss the steady state behavior and the SRZHU Ă RZ DW WKH FRQQHFWLRQ SRLQW WR WKH WUDQVPLVVLRQ grid. While the dynamic requirements concern the desired wind turbine generator behavior during fault and disturbance periods. Generally, these requirements cover many topics such as, voltage operating range, voltage dip, reactive power, power factor regulation, frequency operating range, grid support capability, and low fault ridethrough capability [LVRT] is considered to be the biggest challenge in wind turbines design and manufacturing technology[11]. LVRT requires wind turbines to remain connected to the grid in presence of grid voltage sags. The heavy penetration of grid connected wind cluster is affecting the power quality of power system[12]. Voltage dip is the reduction of the grid voltage with duration of between one cycle or even several seconds[13]. Due to voltage dip the requirement of reactive power is increased, voltage SURĂ&#x20AC;OH LV GHFUHDVHG SRZHU IDFWRU JHWV UHGXFHG +HQFH itâ&#x20AC;&#x2122;s very challenging to maintain the said technical issues under normal and abnormal conditions as per Indian wind grid codes. As per the existing status of voltage dip and reactive power, the custom power device is developed and interfaced with grid connected wind cluster. The PQ enhancement is achieved due to custom power device under voltage dip condition because of not tripping the wind turbines and reactive power management.

An increasing number of power system operators have implemented technical standards known as grid codes that wind turbines must meet when connecting to the

the most important aspect of the electricity supply. Wind energy constitutes 6% of the installed capacity in the power scenario in India. Majority of wind turbines use Induction generators, unlike the conventional generators which are synchronous. Induction generators need VAR support, for which capacitor banks are provided. Inadequate reactive power support will lead to drawl IURP JULG DQG DIIHFW WKH YROWDJH SURĂ&#x20AC;OH DW WKH SRLQW RI interconnection. Grid code sets a standard operating practice for different type of generators. Wind turbines disconnect from the grid when voltage at the point of connection drops. Wind turbines can remain connected to the grid during a fault, only if adequate reactive power support is provided[6,14].The grid codes for wind, in general deal with the following technical requirements: Active power control, Frequency Voltage and reactive power issues, Fault ride through capability, Protection, 3RZHU TXDOLW\ LVVXHV OLNH +DUPRQLFV GLS Ă LFNHU HWF Voltage and reactive power issues: Wind turbines with induction generators need reactive power support. Capacitor banks are the preferred method of reactive power compensation in wind farms. Reactive power drawl from the system can cause increased losses, overheating and de- rating of the lines. Doubly fed induction generators and synchronous generator based wind turbines do not have any constraints with respect to reactive power. The wind farm should maintain a power factor of 0.95 lagging to 0.95 leading[6-14]. Fault/Low voltage ride through: Ability of the wind turbine to remain connected to the grid without tripping from the JULG IRU D VSHFLĂ&#x20AC;HG SHULRG RI WLPH GXULQJ D YROWDJH GURS at the point of connection. Period of fault ride through depends on, magnitude of voltage drop at the Point of Common Coupling (PCC) during the fault, time taken by the grid system to recover to the normal state, During system disturbances, if generators of large generating capacity connected to the grid continue their operation, this aids the system in returning to normal operation. During a fault that causes a voltage drop at the wind turbine terminals, the reactive power demand of induction generators increases. Unless a reactive power support is available at the generator terminals, the reactive power will be drawn from the grid and further instability[6-14].

An example of a typical voltage dip is shown in Fig.1. It commences when the declared voltage drops to a lower voltage than the threshold voltage Vthr (0.9p.u. or 90%.) at time T1, it continues up to T2 at which the voltage recovers to a value over the threshold value.

The magnitude of the voltage dip is Vdip and its GXUDWLRQ LV 7 ĂŽ7 [16]. The causes of voltage dip can be categorized into man-made and natural. Man-made causes (due to human activities on the power network) include switching operations or starting of large motors, power system faults (short circuit), power swings, sudden load changes, generating stations coming on/ off line, unplanned load growth and indiscriminate integration of distributed generation. The natural causes include regulator dysfunction, bad weather, pollution, animals and birds, etc. Impact of Voltage dip: Impact of voltage dip on power system and electrical equipment depends on its severity in terms of magnitude and GXUDWLRQ ,W LV LPSRUWDQW WR EH VSHFLĂ&#x20AC;F ZKHQ WDONLQJ DERXW the dip magnitude or depth.
