Abstract: The present disclosure is directed to a method for preventing a tower strike of a tower of a wind turbine by a rotor blade thereof. The method includes mounting a plurality of sensors circumferentially around the tower at a height generally aligning with a blade tip of the rotor blade in a rotor plane as the blade tip passes through a six o'clock position. Further, the method includes generating, via one or more of the plurality of sensors, at least one distance signal representative of a distance between the blade tip of the rotor blade and the tower as the rotor blade passes by one or more of the sensors. Thus, the method also includes implementing, via a wind turbine controller, a corrective action if the distance signal exceeds a predetermined threshold.
