摘要: Disclosed is a control apparatus for variable-speed hydraulic power generating system comprising a.c. electric generator connected to an and machine including water turbine driving the guide vane controlling amount of supplied turbine. The comprises frequency converter between from system, means operating in response at least externally applied generation command signal controlling, on one hand, thereby generating, other guide-vane opening turbine, reducing resonance which may occur when rotation speed changes change output signal.
