Efficiency Improvement of Permanent Magnet Rotating Electrical Machine (PMREM) with Permanent Magnet Material Selection Manpreet Singh Manna*, Naveen Kumar Pal Department of Electrical & Instrumentation Engineering,Sant Longowal Institute of Engineering and Technology, Longowal, Punjab, India Abstract There are many Permanent Magnet Machines available in the market with the different type of PM material. The rare earth permanent magnet material changes the whole scenario of the market. In comparison with SmCo and AlNiCO magnets, NdFeB magnets have low corrosion resistance. Their chemical reactivity is similar to that of alkaline earth metals like magnesium. Under normal conditions the NdFeB reacts slowly. The reaction is faster at higher temperatures and in the presence of humidity. In this paper the Finite Element model of Rotating Electrical machine simulated using FEM based software for all the three permanent magnetic materials to find the optimum design for achieve higher efficiency of the machine with same dimension and supply conditions. The comparative analysis was computed for different electromagnetic characteristics viz. magnetic flux, current density norm, magnetic energy density etc.

Keywords: Rare earth permanent magnet, PMREM-permanent magnet rotating electric machine, finite element method, efficiency improvement of REM (rotating electric machine)

Integrated Maximum Power Point Tracking and Harmonic Reduction in a Grid Interactive Solar PV Inverter Adil Sarwar1*, M.S. J Asghar2 1

Department of Electrical Engineering, GCET, Greater Noida, India 2 Department of Electrical Engineering, AMU, Aligarh, India

Abstract A solar photovoltaic (PV) cell exhibits a non-linear i-v characteristic and its maximum power point (MPP) varies with solar insolation and temperature. A dc-to-dc converter is generally employed along with inverter circuit to operate the solar PV system at maximum power point. This adds to the cost, which increases significantly with the size of the system. Moreover, grid-tie inverter employing thyristors has square wave line current which is rich in harmonic contents. Pulse Width Modulation (PWM) based inverters employing IGBT or MOSFET are less reliable and has low power handling capability. The paper describes a converter topology employing discontinuous phase control technique for a solar PV based grid-tie inverter. The system is simulated by SIMULINK/MATLAB and the performance is experimentally verified. There is substantial reduction in harmonics of the line current which can be further reduced by filters. The developed control algorithm does away with the dc-dc converter needed for maximum power point tracker (MPPT). Thus, one conversion unit of dc-to-dc converter is avoided to control MPP.

Keywords: Discontinuous conduction, grid tie inverter, maximum power point tracker, total harmonic distortion

Intelligent Baby Monitoring System: A Review Savita P. Patil*, Manisha Mhetre Vishwakarma Institute of Technology, Pune, India Abstract Now a day in India both the parents need to work and look after their babies/infants, so more workload and stress is there on such families especially on female counterparts. If a system is developed which continuously gives updates about their infants during illness or during normal routine then it will be of great help to such members as they can work in stress less environment giving more fruitful output. Also emergency condition can be quickly be noticed and handled within less time. Usually, when a young baby cries, the cause is one of the following things, i.e., they are hungry, tired, not feeling well or need their diaper changed. So there are many such systems available which can monitor the activities of the babies and/or infants along with finding one of the above causes and give this information to their parents. This paper mainly give review on many papers and patents about different babyâ&#x20AC;&#x2122;s vital parameters that need to monitor, different methods for monitoring those parameter and communication methods.

Use of Single Time Reference Measurements of Bus Variable in the Determination of Voltage Instability Condition of a Power System Durlav Hazarika* Electrical Engineering Department, Assam Engineering College, Guwahati, Assam, India Abstract The paper describes a measurement based voltage stability index for monitoring of voltage stability condition of a power system. For this purpose, it is required to measure the voltage and reactive power of a target/selected (bus under investigation) along with the voltages of the other buses connected to the target/selected bus for a single time instant. These measurements and transmission line parameters for the lines connected to the target/selected bus are used to determine the voltage stability index for the target/selected bus. The validity and applicability of the proposed method has been established through simulation on IEEE 30 and IEEE 118 bus system.

Keywords: Voltage stability, power system, index, system variables
