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.

A method for controlling yawing of a wind turbine, the method comprising:
- determining, by a processor, an efficiency information based on previous yaw activities within a defined time interval in the past, wherein the efficiency information reflects a relationship between an effective angular change between at least two yaw positions of the previous yaw activities;
- determining, by the processor, a corresponding accumulated angular movement between the at least two yaw positions;
- and
- controlling, by the processor, yawing of the wind turbine based on the efficiency information.
A wind turbine, comprising:
- a processing unit that is arranged for:
- determining an efficiency information based on previous yaw activities within a defined time interval in the past, 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;
- and
- controlling yawing of the wind turbine based on the efficiency information.
