Harmonic reduction analysis for electric arc furnace using passive filters and DSTATCOM

Abstract

The Industrial furnaces are used globally for wide range of applications from lab scale to complete production lines. They provide continuous high temperatures of 300°C to 3000°C with precise control of temperature and material flow to ensure consistent and uniform output. The furnace operators that deliver at higher efficiencies are prone to power supply system challenges with greater potential for power quality implications on supply system. Hence such operators of high intensity power furnaces should consider design and development of appropriate mitigation techniques to upgrade the power supply quality. In this paper the mitigation of harmonics in Electric Arc Furnace is dealt with suitable passive filter and DSTATCOM techniques. Also, the performance analysis of Electric Arc Furnace has been carried out with MATLAB/SIMULINK based model using Sinusoidal pulse width modulation, hysteresis and the sliding mode controllers.
