Verfahren zum Betreiben einer Windenergieanlage und eine zugehörige Windenergieanlage

摘要

The invention pertains to a method of operating a wind power station, especially to limit the load on a wind power station, preferably a pitch-controlled wind power station. The invention also pertains to a corresponding wind power station. The invention is designed to increase the output of a wind power station and yet limit the load on the wind power station at very high wind velocities. This is accomplished by reducing the power of the wind power station as a function of wind velocity as of a predetermined wind velocity, preferably by reducing the operating velocity of the rotor of the wind power station when a wind appears with a wind velocity above a maximum wind velocity or maximum velocity in the blower stream.
