Single-phase shunt active power filter with knowledge-based harmonic detection algorithm

Abstract

An advanced active power filter for the compensation of instantaneous harmonic current components in nonlinear current loads is presented in this paper. A novel signal processing technique using an adaptive neural network algorithm is applied for the detection of harmonic components generated by nonlinear current loads and it can efficiently determine the instantaneous harmonic components in real time. The validity of this active filtering processing system to compensate current harmonics is substantiated via simulations.
