Abstract:
A wind turbine and a method of controlling yawing of a wind turbine are provided. A nacelle is mounted rotatable around a first axis by an adjustable yaw angle and a hub is mounted rotatable around a rotational axis. The hub includes a blade rotating around the rotational axis, the blade defining a rotor plane perpendicular to the rotational axis. A channel of the wind turbine has an opening, the opening being located at a predefined distance to the rotor plane. At least one component of incoming wind is guided through the opening and into the channel as air flow. A measuring device is provided for measuring the air flow, the measuring device being connected to a controller. The controller detects a yaw angle error between a direction of the incoming wind and the rotational axis, the yaw angle error being used to adjust the yaw angle of the nacelle.
