Comparison of Various Harmonic Mitigation Techniques in Induction Furnaces

Abstract

AbstractHarmonics are a necessary evil associated with non linear loads such as Induction furnaces. As the amount of non linear loads in power system is increasing due to pro-filtration of non linear devices such as inverters, inductive loads etc.; it is leading to a deterioration of power quality. Non linear loads tend to inject harmonics in the power system. Induction furnaces are a major non linear load as far as our power system is concerned. This paper is an attempt to compare the various techniques of harmonic mitigation employed for mitigating harmonics in induction furnace.KeywordsHarmonicsVoltage and Current HarmonicsHarmonic Mitigation
