Abstract
An apparatus and method for controlling a wind turbine having a plurality of blades such that the blade angle of each blade is continuously adjusted during loss of grid power relative to a wind direction relative to an orientation of the nacelle (i.e., yaw offset) and a rotor azimuth while keeping the orientation of the nacelle of the wind turbine substantially constant. The wind turbine is capable of pitching the blades a full 360 degrees and generating power from the rotation of the rotor shaft during loss of grid power.
