Abstract

A method (100) for reducing loads of a wind turbine (10) includes determining an operational state of the wind turbine (10). The method (100) also includes commanding a predetermined pitch event. Further, the method (100) includes monitoring at least one operating condition of a pitch drive mechanism (32) of a rotor blade (22) of the wind turbine (10) during the predetermined pitch event. If the operational state corresponds to a predetermined operational state and the operating condition(s) follows a pitch fault pattern during the predetermined pitch event, the method (100) also include yawing a nacelle (16) of the wind turbine (10) away from an incoming wind direction.
