摘要: A variable-speed pumped-storage power generating system includes a generator/motor, frequency converter connected to an electric system, and pump/turbine driven by the generator/motor. The comprises optimum rotation speed function generator calculating of motor for driving pump, detector detection signal motor, regulator receiving output signals from correction signal, adder adding command comparator comparing with generated error controlling excitation secondary winding through so as decrease zero, thereby motor. generatign also guide-vane opening guide vane opening, detector, vanes according result comparison.
