Claim 21:
22. A wind power installation, comprising:
a rotor;
at least three rotor blades having respective blade angles that are individually adjustable;
a sensor configured to detect, for each rotor blade of the at least three rotor blades, an actual blade angle; and
a controller configured to:
determine a blade malposition of a rotor blade of the at least three rotor blades 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.
