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.

1. A wind turbine generator system comprising, a nacelle mounted atop a tower,a main shaft mounted in the nacelle and having a rotor head to which wind turbine blades are attached, the main shaft and the wind turbine blades integrally rotating,a gear box attached to the main shaft, and accelerating and outputting the rotation speed of the main shaft,a generator driven by the output of the gear box, anda controller that performs cut-out control during strong wind when a measured value from an anemometer is a predetermined level or more, the controller being 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,wherein the controller is operatively connected with an outside air temperature sensor and configured to use a detection value of outside air temperature for deciding that the anemometer has a fault. 2. The wind turbine generator system according to claim 1, wherein the controller is configured to perform cut-out control and stops generation of electricity when it is decided that the anemometer has the fault. 3. The wind turbine generator system according to claim 1, wherein the controller is configured to perform cut-out control and stops generation of electricity when it is decided that the anemometer has the fault. 4. A wind turbine generator system comprising, a nacelle mounted atop a tower,a main shaft mounted in the nacelle and having a rotor head to which wind turbine blades are attached, the main shaft and the wind turbine blades integrally rotating,a variable pitch mechanism for changing a pitch angle of the turbine blades,a gear box attached to the main shaft, and accelerating and outputting a rotation speed of the main shaft,a generator driven by the output of the gear box,an anemometer attached to the nacelle, anda controller that performs cut-out control during strong wind, the controller having means for obtaining a measured value from the anemometer, means for calculating an estimated wind speed value from a relationship between a blade-pitch-angle of the wind turbine blades of the variable pitch mechanism and an output of the generator, and means for determining that the anemometer has a fault when a difference of a predetermined level or more occurs between the measured value from the anemometer and the estimated wind speed value,wherein the controller is operatively connected with an outside air temperature sensor and configured to use a detection value of outside air temperature for deciding that the anemometer has a fault.
