Abstract
Method of reducing loads acting on a wind turbine yaw system in a wind turbine comprising a nacelle (), a rotor which comprises at least one rotor blade () with a pitch control system and further comprising a yaw system that comprises the steps of detecting a yaw misalignment (α), enabling a yaw maneuver and performing a pitch control in order to reduce a yaw moment (Mz) acting on the wind turbine once the yaw misalignment (α) is detected and prior to enabling the yaw maneuver. Thus, when a yaw movement to reduce the yaw misalignment is commanded, the yaw moment (Mz) due to aerodynamic forces has been reduced by means of the pitch control and undesired yaw movements are prevented.
