Abstract:
A method for controlling a wind turbine with rotor blades with an adjustable blade angle, comprising: operating the wind turbine in a part-load operation for wind speeds up to a rated wind speed, operating the wind turbine in a full-load operation for wind speeds above the rated wind speed, with the blade angle being increased in full-load operation with increasing wind speed, setting a limit angle as a minimum value of the blade angle, and controlling the wind turbine in such a way that the limit angle is undershot by at most a predetermined difference angle.
