Harmonic Identification and Mitigation using APF in Distribution System Consisting of Single Non Linear Load

Abstract

This paper presents a unique approach for source side compensation of current harmonics occurred to the presence of nonlinear characteristic loads in power systems by the implementation of Active power filter (APF). This is often as a result of optimizing the ability system networks exploitation typical mathematical modeling based mostly linearized approaches is kind of tough owing to the advanced, nonlinear and non-stationary nature of systems that involve an outsized variety of difference constraints. In order avoid the complexness of conventional concepts in this paper the implementation of Total Harmonic Power (THP) to 2 complete cases with and without APF are proposed i.e. identifying the harmonics and reducing their effect with APF has been planned here to lower down the supply current Total harmonic distortion (THD) sufficiently below fifth order so as to satisfy the IEEE-519 std. even beneath distorted offer. Intensive MATLAB simulations and comparative analysis were applied for cases with and without APF management schemes using THP control techniques.
