Abstract

Due to the advancement of electrical equipment most of the equipment is power electronics-based which is mostly used everywhere. Power electronics device is the main cause for the production of power quality problems, Harmonics are a major issue of power quality. This work describes a shunt passive filter for harmonics mitigation and reactive power compensation. Here single tuned and double tuned passive filters are discussed. It deals with the problem related to harmonics due to the nonlinear load. Three-phase thyristor loads are taken as a nonlinear load. For thyristor 180° scheme is used here. Thyristors are fired for seven different values of firing angle from 0° to 60°. The exhibition of a three-phase shunt passive filter is clarified in this paper. Simulations are carried out using MATLAB/SIMULINK. simulation results are presented.

Keywords- nonlinear load, shunt passive filter, Total Harmonic Distortion (THD), power quality, single tuned filter, double-tuned filter
