Abstract: A rotor blade of a wind turbine, to an associated wind turbine and to an associated method. A rotor blade for a wind turbine, which extends in the longitudinal direction with a profile course from a blade connector to a blade tip, wherein the profile course comprises a course of a lift coefficient, comprising a hub portion adjacent to the blade connector and a tip portion adjacent to the blade tip, a middle portion adjacent to the hub portion and to the tip portion, wherein the middle portion substantially comprises those profile sections which have a relative profile thickness, which is defined as the ratio of maximum profile thickness to profile depth, of between 20% and 30%, and wherein the middle portion comprises a local minimum of the course of the lift coefficient.

Abstract: A method for operating a wind power installation is provided. The wind power installation comprises an aerodynamic rotor with rotor blades, where the rotor can be operated with a variable rotor rotation speed. The wind power installation outputs an output power generated from wind for feeding into an electrical supply grid. The wind power installation can be operated in a normal operating mode without power reduction and in a reduced operating mode with power reduction, in which a specified power reduced with respect to a rated installation power is specified. When operating in the reduced operating mode for wind speeds above a rated wind speed, at least in one rotation speed increase region, the wind power installation increases its rotor rotation speed as the wind speed rises further.
