Design and Implementation of Active Power Filter for Harmonics Elimination using Intelligent Control Controller

Abstract

Non-linear loads generate harmonic current in power system. These harmonics currents can produce various type of effect that is harmful to the power system. A system required to filter out these harmonics. Design and assessment of shunt active power filter (SAPF) for harmonics elimination using intelligent control controller (fuzzy logic) present in this paper. Generally, conventional phase-locked loop (PLL) technique are used for eliminate harmonics. In PLL technique based system contains more harmonic. This paper compared without filter versus with filter at different loads. Results shows that intelligent control controller based system contain minimum harmonic contain as compared to conventional controller
