Comparative Analysis of Power Quality improvement with PQ Theory & DC Link Control Scheme of Non-Linear Load by using Shunt Active Power Filter

Abstract

This paper highlights the harmonics problems which is created by non-linear load and retrieval technique for controlling the current hysteresis controller is used. The harmonic problem causes the effects of equipment damage and Electromagnetic Interference effects in the power system. The expanded hardness of harmonic pollution in power system has attracted the concentration of system engineers to develop a powerful solution to the power quality problems. These equipments known as active filter (AF’s), are also called active power line conditioners (APLC’s). To reduce this problem Shunt Active power filter (SAPF) has more suitable because of its excellent performance of harmonic mitigation, In this paper Different control methods of Active power filter in addition to different harmonic extraction methods are presented and discussed, The simulation result of shunt active filter using PQ theory and DC Link Scheme is carried out using MATLAB/SIMULINK toolbox
