A wind power installation is disclosed comprising a rotor having at least one rotor blade for converting the kinetic energy of the wind into mechanical energy, an adjusting device for individually adjusting at least one rotor blade, a generator for converting the mechanical energy of the rotor into electrical energy, and an operative connection between the rotor and the generator for transmitting the mechanical energy of the rotor to the generator. The disclosed wind power installation therefore avoids specified problems of known installations and provides a wind power installation in which the loadings which can occur due to local, temporary peaks in the wind speed in portions of the rotor area are reduced. Accordingly, in the disclosed wind power installation, there is provided a measuring device which ascertains the instantaneous loading of a part of the wind power installation, a control device which ascertains a position of at least one rotor blade that is desired for the instantaneous loading, and suitably adjust the rotor blade by the adjusting device, and a connecting device which connects the adjusting device and the measuring device to the control device.

1. A wind power installation comprises:a rotor with a rotor hub with at least two rotor blades which are rotatable about the longitudinal axis; an adjusting device for individually adjusting a rotor blade to a desired blade setting angle; a generator which is operatively connected to the rotor; said rotor hub is provided with measurement means for ascertaining at least one of the instantaneous mechanical loading of the hub or a rotor blade; control means for ascertaining a blade angle position which is wanted for the reduction in the instantaneous loading using a variation in the instantaneous blade angle position of at least one rotor blade and which suitably adjust the rotor blade to the desired blade angle position by the adjusting device asynchronously from the blade angle position of other rotor blades; and said adjusting device and said measuring means being connected to the control means.
