Multi Objective Visual optimization of SFC Starting Control System for Synchronous Generator

Static frequency converter (SFC) is widely applied in the pump storage power plant synchronous generator units. However, adjusting PI control of speed-current double closed loop is a very difficult problem. A multi objective visual optimization method is proposed, the speed and current closed loop control can be optimized according to the performance specifications. The SFC starting control model is established, and D-partition technique is applied to obtain the PI parameters stable region respectively. Besides, multiple performance specifications of current loop control is analyzed. And most importantly, the PI parameters of speed-current double closed loop can be selected from the optimization area. Experimental results verify the proposed method of effective and practical.
