Abstract
Provided is a method for identifying a blade malposition of a rotor blade of a wind power installation having one rotor and at least three rotor blades which in terms of the blade angles thereof are individually adjustable. For each rotor blade an actual angle is detected as the actual value of the blade angle; and the blade malposition is identified as a function of a blade angle deviation of the rotor blade and a rotational progress of the rotor. The blade angle deviation describes a deviation of the actual angle from a reference angle, and the rotational progress is representative of an angle about which the rotor has rotated onward after a start criterion. Blade malpositions in rotor blades which in terms of the blade angles thereof are individually adjustable are identified rapidly and reliably.
