A method and an apparatus for adjusting a yaw angle (106) of a wind turbine (100) comprising a rotor having a plurality of rotor blades (101) and a hub (104) are provided. The method is adapted for adjusting the yaw angle (106) from an actual yaw angle to a desired yaw angle and comprises the steps of measuring a wind direction (105) at the location of the wind turbine (100), measuring the yaw angle (106) of the wind turbine (100) and/or a wind direction relative to the nacelle orientation, calculating a pitch angle (108) of at least one rotor blade (101) as a function of the measured wind direction (105) and the measured yaw angle and/or a wind direction relative to the nacelle orientation, and adjusting the pitch angle (108) of the rotor blades (101) according to the calculated pitch angle (108) such that a yaw momentum (107) is generated for changing the yaw angle (106) from the actual yaw angle to the desired yaw angle. |
