Claim 0:
1. A method for identifying a blade malposition of a rotor blade of a wind power installation,
wherein the wind power installation has one rotor and at least three rotor blades having respective blade angles that are individually adjustable, and
wherein the method comprises:
detecting, for each rotor blade of the at least three rotor blades, an actual blade angle; and
determining the blade malposition based on:
a blade angle deviation of the rotor blade, and
a rotational progress of the rotor, wherein:
the blade angle deviation represents a deviation of the actual blade angle from a reference angle, and
the rotational progress represents an angle about which the rotor has rotated onward after a start criterion.
