OPERATION CONTROL METHOD FOR WIND POWER GENERATOR

PROBLEM TO BE SOLVED: To provide an operation control method for a wind power generator, in which a generator G is installed on the ground, a flexible control of operation of the wind power generator, and rotation of a windmill 1 can be suppressed without losing wind power energy. SOLUTION: In the operation control method for a wind power generator employing a hydraulic system for transmission of rotational energy, at least one of a hydraulic pump 13, hydraulic motor 15, hydraulic motor 20 is a variable displacement type. A controller 10 is constituted of a revolution number detection means of the windmill 1 and a predetermined electronic control circuit. When receiving a revolution number detection signal of the windmill 1, the controller 10 outputs a control signal based on set operational specifications to perform a variable control of the capacity of a variable displacement hydraulic pump 13 or the hydraulic motor 20.
