Abstract
A method for operating a wind turbine is provided, wherein the wind turbine includes a rotor and plurality of blades configured for rotating about a rotor axis such that a rotor disk is defined by a circular area swept by the blades. The wind turbine includes a nacelle, a tower, and a yaw system configured to yaw the nacelle and the rotor about a longitudinal axis of the tower. The method detects or predicts a fire in a first one of the blades and adjusts an azimuth angle of the rotor about the rotor axis such that the first blade is positioned in an upper half of the rotor disk. The nacelle and rotor are yawed away from an incoming wind direction to a yaw angle of more than 90 degrees and less than 270 degrees.
