Combined system of Static VAR Compensator and Active Power Filter for Harmonic Suppression and Power Factor improvement

Abstract

In this paper the combined system for power quality improvement is proposed. The system consists of Static Var compensator and Shunt active power filter for harmonic suppression, power factor correction and voltage stability. The configuration and the control method for the Static Var compensator is proposed. An optimal non-linear PI controller is proposed to improve the performance of the Static Var compensator and the improved generalized integrator controller is proposed to improve the performance of the APF. The simulation results of the non linear systems have been carried out with Matlab 7.6.
