Abstract:
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.
