ABSTRACT:
A method and apparatus for controlling a variable-speed hydraulic power generation system using an induction generator of wound-rotor type is disclosed, in which variation in frequency of the power system connected to the power generation system or power demand from the power system is detected and the detected value is applied to a control unit for controlling the guide vane of a hydraulic machine driving the generator, thereby dampening variation in frequency or power balance of the power system.
