Patent ID: 7476985

Claim:
An operating method for a wind turbine which comprises a wind vane and an anemometer located at a nacelle of the wind turbine; a group of sensors selected from the group of strain gauges, accelerometers, pilot tubes, hot film sensors, and laser light or ultrasound sensors assembled on one or various blades; at least one of temperature, acceleration, and vibration sensors located on at least one of a drive train and a generator; acceleration, movement, or vibration sensors located on at least one of a tower of the wind turbine, its substructures, and the nacelle; and a system for measuring output power of the generator, the method comprising: reducing at least one of the speed of a rotor and the power of the generator when wind impacts the wind turbine at a speed of more than 25 m/s or in swell conditions for offshore wind turbines, in response to a plurality of variables formed based on the wind direction in relation to the horizontal direction of a main wind turbine shaft and on the wind turbulence.
