Abstract: Due to the fast response feature, DSTATCOM is becoming the major choice for electric arc furnace (EAF) compensation. An instantaneous current control strategy for delta-connected chain circuit DSTATCOM is proposed. Based on the EAF simulation platform constructed with recorded field data, the control strategy is studied with digital simulation and real-time digital simulation. The simulation results given in the paper show that the proposed control strategy can effectively compensate the unbalanced and harmonic load current of electric arc furnace.
