Study and Simulation of the Effect of Three-Phase Parallel Active Filter in Low Voltage Distortion Power Systems
Active shunt filters compensate for current harmonics by injecting equal but opposite harmonic compensating current. The active shunt filter acts as a current source that injects the harmonic components produced by the load, but its phase is shifted 180 degrees. In this paper, the performance of a three-phase parallel active filter without the use of a capacitive bank is investigated and the results are evaluated technically and economically. Simulation results have been obtained using Simulink in MATLAB software. The simulation results show that the power factor correction is done without any harmonic resonance and the source is the only active power generator and the reactive power compensator is responsible.
