METHOD FOR OPERATING A WIND TURBINE, WIND TURBINE, AND CONTROL MEANS FOR A WIND TURBINE

摘要

In the case of wind turbines 10, deviations from the optimum operating state result in output losses. This applies, in particular, to angular deviations 62 in the alignment of the nacelle 14, and therefore of the rotor axis 28, relative to the wind direction 60. The invention relates to a wind turbine 10, and to a method for operating such a wind turbine, which wind turbine and method enable the nacelle 14 to be corrected, in respect of the wind direction, both on the basis of wind power and by motor.

1. A method for operating a wind turbine (10) having a rotor (20), which is mounted on a rotatably mounted nacelle (14) and which has a least one or more rotor blades (22, 24), characterized in that an angular deviation (62) of the nacelle position from a setpoint position is determined, wherein the angle of attack of each of the rotor blades (22, 24) is adjusted individually and/or continuously, in such a manner that the nacelle (14) is made to rotate for the purpose of correcting the rotor axis (28) into the setpoint position.
