Abstract:
A method for controlling yawing of a wind turbine, wherein an efficiency information is determined based on previous yaw activities, wherein the efficiency information reflects a relationship between an effective angular change between at least two yaw positions of the previous yaw activities, and a corresponding accumulated angular movement between the at least two yaw positions, wherein the yawing is controlled based on the determined efficiency information is provided. Further, a wind turbine and a device as well as a computer program product and a computer readable medium are suggested for performing the method is also provided.
