Improvement of Power Quality in an Electric Arc Furnace Using Shunt Active Filter

Abstract

Stochastic performance of an electric arc furnace (EAF) and its associated power quality constraints has drawn the attention of the researcher’s. In this paper, the power quality disturbances are investigated by characteristic modeling of an electric arc furnace and shunt active filter is incorporated with the system to suppress the effect of these disturbances. The nonlinearity of an EAF load results in distortion of the fundamental component leading to the occurrence of voltage flicker, harmonics, and inter-harmonics. The simulation studies are carried out in MATLAB (Simulink).
