Harmonic Estimation and its Compensation using D-STATCOM for a Steel Manufacturing Plant

Santosh Kumar Singh, Amarjeet Singh

Abstract


Electrical power system having distorted voltage and current waveform generates harmonics. The compensation of the harmonics is greatly required for better performance of the power system. Harmonic is of major concern for the power system containing electric arc furnace (EAF). Since the nature of the arc is highly non-linear and time varying and therefore harmonic analysis becomes important to know the behavior of the power system. This paper presents the estimation of harmonics generated by the steel plant containing arc furnace and its auxiliary units such as ladle melt furnace, continuous casting unit, rolling mills and forging press during different stages of melting of iron scrap and also its compensation by implementing Distribution Static Compensator (D-STATCOM) so that the level of the harmonics are within the standard set by IEEE 519-1992. The Synchronous Rotating Frame (SRF) Theory has been applied control D-STATCOM
