Abstract Accurate calculation of magneto motive force and electromagnetic torque and the initial rotor position detection are the important prerequisite for the success of the starting operation of the generator motor. The reasons for the PID controller failure of forced commutation of 2 static frequency converter (SFC) driving generator motors in Jiangsu practical pumped storage power station are proposed. Then, the coordinated control strategy of SFC and excitation system, SFC and computer supervisory control system is proposed, using flux linkage equation to determine the initial rotor position, which can greatly improve the debugging efficiency of pumping phase modulation drive stage. At the same time, an improved relay protection setting method for SFC system is proposed to prevent the malfunction. The practical application results show that this methods has a good engineering application prospect.
