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

The method is for operating a wind turbine (100) having a rotor (10) with at least two rotor blades (1, 2, 3), a tower (20) and a pitch setting system (13). The method comprises a step, in which first information is provided which is representative for bending moments of the at least two rotor blade...

Zusammenfassung:	The method is for operating a wind turbine (100) having a rotor (10) with at least two rotor blades (1, 2, 3), a tower (20) and a pitch setting system (13). The method comprises a step, in which first information is provided which is representative for bending moments of the at least two rotor blades and the assigned positions of the rotor blades. In another step, second information is provided which is representative for maximum allowed bending moments of rotor blades when they are in a critical sector close to the tower. In yet another step, third information is determined depending on the first and the second information which is representative for whether the bending moment of at least one rotor blade exceeds the respective maximum allowed bending moment when said rotor blade is in the critical sector. If this is the case, an output signal is generated which is configured to cause the pitch setting system to individually change the pitch angles of the rotor blades in order to reduce a deflection of the rotor blades towards the tower when they pass the tower.
