ルトン水車の運転装置。[Claims for Utility Model Registration] (1) The deflector and needle of the Pelton water turbine are each provided with an electrically operated servo and a deflector and needle servo control unit that drive these servos, and the rotational speed of the water turbine is adjusted in accordance with the deflector. A speed governor control unit that generates speed governor control commands based on signals, speed governor setting device output, and load adjustment setting device output, and inlet valve opening, starting, uniform speed/parallel, water control operation mode during normal operation, A deflector operation mode changeover switch is provided, which is turned on and off based on the accident stop mode, and selectively sends the governor control section output or the fully closed command to the deflector servo control section, while a load adjustment setting device is provided corresponding to the needle. A needle control unit that sends an opening command based on the output, and a needle control unit that is turned on and off based on the inlet valve opening during normal operation, needle water adjustment, starting, equal speed/parallel, water adjustment operation mode, and accident stop mode, and the needle A needle operation mode changeover switch is provided to selectively send a control unit output or a full-close command to the needle servo control unit, and the deflector and needle of the Pelton water turbine are individually controlled according to the various operation modes. Pelton turbine operating system. (2) A deflector that inputs a deflector opening signal and a needle opening signal into the needle control unit, generates a needle opening command according to the deflector opening signal, and outputs a deviation from the needle opening signal. The needle opening setting circuit is turned on and off based on an interlock/individual control switching command that selects between the individual control and the interlocking control that keeps the needle opening at an opening commensurate with the deflector opening and follows the deflector opening. An interlock/individual control operation mode switching switch is provided to selectively send the output of the needle opening setting circuit and the output of the load adjustment setting device to the needle servo control section, and the deflector and the needle can be operated in conjunction or individually. 2. The Pelton water turbine operating device according to claim 1, wherein the control is performed according to a mode.
