Abstract

Monitoring and supervision is an important aspect in view of security of an interconnected power system. The work presented here gives a comparison of various advanced state estimation techniques for optimal placement of Phasor Measurement Units in Power Networks. These techniques meet two requirements i.e. to ensure the complete system observability and at the same time find the optimal locations of Phasor Measurement Units with the minimum cost. The problem is formulated as a mono-objective optimization problem and its resolution is made by implementing seven algorithms which are mentioned in this paper. The proposed algorithms are demonstrated using five test networks that include a practical system. The simulation results ensure the complete system observability.

Abstract

The problem of voltage deviation and power loss is mostly addressed in distribution system by growing domestic, industrial and commercial load day by day. To minimize these problems, effective planning of distribution system is required. This effective and reliable planning of distribution system is achieved by optimized placement of control device (capacitor) in distribution networks. The idea for optimal capacitor placement is determined that location of the capacitor is to be installed in the distribution network buses where power losses should be minimum and cost saving should be maximum. This paper presents a new and efficient approach for capacitor placement in radial distribution systems that determine the optimal locations and size of capacitor with an objective of improving the annual cost saving, the voltage profile and reduction of power loss. The solution methodology includes an algorithm that employs Plant Growth Simulation Algorithm (PGSA) and Genetic algorithm to estimate the optimal size of the capacitors at the optimal buses determined. The effectiveness of the proposed method is applied to 33 and 69 bus IEEE radial distribution systems. Result shows that after placement of capacitor in candidate buses the energy loss has been reduced.

Abstract

This paper proposes speed control of permanent magnet linear synchronous motor using Space Vector Pulse Width Modulation (SVPWM). Among the various modulation strategies Space Vector Modulation Technique is the efficient one because of its better spectral performance, better dc bus utilization and easier digital realization. With SVPWM the performance of PMLSM is improved because it eliminates all the lower order harmonics in the output voltage of the inverter when compared to the conventional SPWM technique. The open loop & closed loop simulation model for SVPWM with PMLSM is constructed using MATLAB/SIMULINK. Hardware is implemented and validated Using dSPACE ds1104 controller board.

Abstract

The D-STATCOM is a shunt connected FACTS device which supplies reactive power to the load to improve the voltage stability of the load buses. The D-STAT COM in multi bus system is capable of reducing the losses and improving the voltage regulation. This work deals with the comparison of Push Pull and Voltage Inverter based D-STATCOM for multi bus system. Eight bus system is modeled using the elements of SIMULINK. The models are developed for eight bus systems with and without D-STATCOM. The two D-STATCOM systems are compared with respect to total harmonic distortion and reactive power comparison. The D-STATCOM is studied with respect of the voltage stability improvement at the load buses. The results of VSI based D-STATCOM system are compared with those of Push pull inverter based D-STATCOM system.

Abstract

In this work the authors propose a novel approach in modelling and controller design of the synchronous dc-dc step down converters. Power electronic converters are mainly periodic variable systems due to their variable switched systems. The generalized or enhanced the state space averaging is a better approach than the state space averaging as it defines them by a unified set of differential equations, capable of representing circuit waveforms. This model is then used to design a PID controller which will help us in understanding the converter dynamics.
