Abstract
Among the various power quality problem, current harmonics are most
commonly seen on the power system. This is mainly due to increased application of nonlinear
loads by the end users. In this paper, an analysis and simulation of a PV interactive
shunt power active filter (SPAF) is done for single phase system. The shunt active power
filter is used to eliminate harmonics generated by the nonlinear load. During the day-time
with intensive sunlight, the PV interactive Shunt Active Filter system brings all its functions
into operation. At night and during no sunlight periods, the power required by the loads is
received from the distribution system while the inverter system only provides reactive
power and filter harmonic currents. For the Shunt Active Filter reference current
computation, the instantaneous real and reactive current (Ip-Iq) method is used. For gating
signal generation we apply the hysteresis current control technique. The Simulation results
(using MATLAB/SIMULINK) are presented and discussed. The proposed solution has
achieved a low THD (Total Harmonic Distortion), demonstrating the effectiveness of the
presented method.
