Optimal Capacity of SVC to Compensate Flicker Induced by Electric Arc Furnace

Electric arc furnaces are one of the most severe sources to induce voltage flickers and hard to make an analysis model due to its chaotic characteristics. In this paper, a practical modeling strategy for electric arc furnaces is suggested. By using this model, the flicker phenomena induced by electric arc furnaces are simulated and analyzed to find out solutions for compensation. To compensate voltage variation and frequency fluctuation, we used SVC devices and suggested a novel scheme to identify the optimal capacity of SVCs by using Pst flicker index which is suggested on IEC standards.
