In this paper

the performance of the series capacitor compensation of the submerged arc furnace is analyzed and studied. It is shown that the series capacitor compensation of the submerged arc furnace can compensate effectively power factor

improve effective power significantly

enhance effective output of the furnace by 30%

40% and decrease significantly per unit yield energy consumption. The stability and the reliability of series compensation mode are analyzed. The capacitor neither needs to bear the impact due to frequent operation nor to group and the cost of the product reduces significantly.
