Abstract
A method for determining at least one blade misposition of a rotor blade of a rotor of a wind power installation having multiple rotor blades with an adjustable blade angle, wherein the blade misposition describes a blade angle variance of the blade angle of the rotor blade from a reference blade angle, the wind power installation has a nacelle having the rotor and an azimuth adjustment device, wherein a circumferential rotational position of the rotor is referred to as the rotor position, and the azimuth adjustment device has at least one activable azimuth actuator in order to adjust an azimuthal position of the nacelle, comprises the steps of a detection step comprising detecting an azimuthal movement of the nacelle while the at least one azimuth actuator is inactive, and a determination step comprising determining the blade misposition on the basis of the azimuthal movement detected in the detection step.
