US Patent 7566982 Method for controlling and adjusting a wind turbine

A method for controlling and adjusting a wind power installation having a nacelle displaceable by an azimuth angle, at least one rotor blade displaceable about its longitudinal axis and a power supply in a spinning mode, wherein the method comprises the following steps: a control unit determines an angular position for the nacelle from measured values (v) of wind velocity and wind direction and one or more displacement angles for the at least one rotor blade upon a measured wind velocity exceeding a predetermined speed value (v1*, v2*), at least one azimuth drive fed by the power supply sets the nacelle into the angular position (α) determined by the control unit, and at least one pitch drive fed by the power supply sets the at least one rotor blade into the angular position (φ) determined by the control unit, wherein the at least one rotor blade rotates in the set position at a rotational speed within a predetermined range of rotational speed.
