ABSTRACT:
An apparatus for controlling a water turbine is disclosed wherein an auxiliary servomotor having a capacity substantially equal to that of a servomotor for actuating pressure regulator is provided for actuating flow control guide vanes, the auxiliary servomotor for the guide vanes and the servomotor for the pressure regulator being connected through pipe lines. The guide vanes for the water turbine are controlled according to a position of an auxiliary servomotor for the governor and the servomotor for the pressure regulator is controlled according to a difference between the opening position of the guide vanes and the set position of a load limiter for the water turbine. At the time of free running of the water turbine utilizing the governor, the pressure regulator is operated in response to the open- and closing operation of the guide vanes to suppress any variation in the water flowing speed in a penstock, and at the time of the load-limiting operation of the water turbine, the pressure regulator is fully closed for minimizing ineffective flow of water.
