Study harmonic injections by residential customers

Abstract

This paper describes a method of modeling harmonic current injected residential electrical loads. The models were developed using the experimental results from the commercially available equipment commonly use in residential installations like compact fluorescent lights, television, personal computer, VCD player, printer and notebook. It is important that to determine harmonic levels and analyze system data so that we can implement the model of harmonic. Harmonic currents produced by non-linear loads are injected back into the supply systems. These currents can interact adversely with a wide range of power system equipment, most notably capacitors, transformers and motor, causing additional losses, overheating and overloading. The data and result from the experiment which done at “Kluster Penyelidikan” by using CTS WIN2100V3, will be applied to model the single line diagram of harmonic current injection. This modeling stage will be done by using MiPower Software.
