An Improved PSO Based Selective Harmonic Elimination in Multilevel Inverter for Performance Enhancement of Induction Motor Introduction
Harmonics measurement of an industrial unit is done to asset the power quality aspects in a typical factory. Then with using a lumped steady state and thermal model we analyzed the influences of different harmonics on motor temperature rise. The real issues are the harmonics generated by the inverters which affects the induction machine performance. Several inverters like Voltage Series Inverters, PWM fed Inverters, Multilevel inverters etc. exist in literature. Among all these, multilevel inverters have been very popular of late due to its several advantages. But there is a challenge of optimal design of the inverter and optimal selection of pulse width of each level so as to get minimal Total Harmonic Distortion. This paper discusses various works done by researchers in this field over the course of time. For these reasons a novel multilevel inverter design based on an improved Particle Swarm Optimization is proposed in this thesis for obtaining the optimal width of the pulse of each level so as to get minimal Total Harmonic distortion. A Simulink model of the improved PSO modified multilevel inverter will be created and fed to an induction motor and the FFT analysis of the voltages and current will be done to evaluate the performance of the induction machine. The results will be compared to that of the existing techniques. All the simulations will be performed in MATLAB software.
