Abstract
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.
