摘要：

A converter-fed adjustable-speed generator-motor for a pumped storage power plant has been developed in order to contribute to the automatic frequency control on an electric power system during pumping operations, as well as; to improve the efficiency of turbines during generating operations together with stability.; This system consists of a reversible pump turbine, a generator motor, cycloconverter and control-units. The rotor of the generator motor, which is coupled directly with the turbine runner, normally is operated at a rotating speed which is equal to the difference between the frequency of the electric power system and that of the rotor current. In the state that a fault has occurred in the primary circuit of the generator motor, the adjustable-speed generator-motor fault current differs from that of a conventional synchronous generator motor.
