Abstract

This paper presents a control algorithm for improving the performance of a three-phase, four-wired (3P4W) active power filter (APF) under unbalanced and distorted supply voltages. A low pass filter (LPF) is designed to filter the nonsinusoidal supply voltages. The minimal optimal values of active power filter source reference currents are estimated in natural a-b-c reference frame. The proposed method is capable for harmonics suppression, reactive and neutral current compensation and load balancing in three-phase four-wire (3P4W) distribution systems. Extensive simulation is carried out under MATLAB Simulink environment. Various simulation results are presented with ideal and distorted mains condition to show the effectiveness of the algorithm.
