摘要： An accumulator is provided in an oil circuit of the pressure supply device and has a gas chamber for storing the pressure generated by the oil pump. A gas pressure judgment unit judges a soundness on the gas pressure of the gas chamber of the accumulator. A pitch movement judgment unit judges whether the pitch movement is performed soundly by the oil pressure accumulated in the accumulator if the gas pressure judgment unit judges that the gas pressure is sound. A start judgment unit judges a start condition to start the gas pressure judgment unit every predetermined period or when a start switch is operated.

摘要： A wind turbine generator system includes, in a nacelle mounted atop a tower, a main shaft that is coupled to a rotor head to which wind turbine blades are attached and that integrally rotates therewith, a gear box accelerating and outputting the rotation speed of the main shaft, a generator driven by the output of the gear box, and a controller that performs cut-out control during strong wind when a measured value from an anemometer is a predetermined level or more. The controller is configured to decide that the anemometer has a fault when a difference of a predetermined level or more occurs between the measured value from the anemometer and an estimated wind speed value obtained from a relationship between a blade-pitch-angle of the wind turbine blades and an output of the generator.
