Traditionally when one imagine about power quality, images of classical waveforms comprising 3rd, 5th, 7th etc. harmonics come into picture. Reactive-power compensation, Harmonic compensation, harmonic isolation, harmonic damping, and harmonic termination, Negative sequence current/voltage compensation, Voltage regulation. The terminology active filters are often seen in different fields apart from power processing.
In this work both PI controller based and Hysteresis Band controller, three phases SAPF is used to compensate harmonics and the reactive power by a non linear load to better the quality and is implemented on three phase wire system. The simulation of the results done through MATLAB program, and number of simulation results of the method are observed under steady conditions.
