Abstract:
1. A method of controlling the yaw motion of a two-bladed wind turbine, the wind turbine comprising a yaw-able nacelle to which a wind turbine rotor is rotatably mounted, said wind turbine rotor having first and second rotor blades mounted to a hub which defines an axis of rotation around which said wind turbine rotor rotates, the method comprising the steps of: yawing the wind turbine nacelle at a yaw speed to adjust the orientation of the wind turbine rotor blades with the oncoming wind at the wind turbine, wherein the method further comprises the step of: adjusting said yaw speed based on the rotational position of the wind turbine rotor blades about said axis of rotation when the wind turbine is operating in a power generation mode.
