Abstract: A method of calibrating a yaw actuator of a wind turbine is provided, including steps of performing an active yaw operation in a clockwise yaw direction and an active yaw operation in a counter-clockwise yaw direction; recording data of a wind direction and a power caused by both yaw operations, and averaging the data and calculating an error between an experimental power difference and a theoretical power difference of yaw operations in the clockwise direction and a counter-clockwise direction; determining a minimum of the error; and determining a yaw misalignment based on the minimum error.

Abstract: A sealing arrangement of a wind turbine is provided including an axial seal, a stationary member and a generator rotor for sealing a gap between the stationary member and the generator rotor. Accordingly, the stationary member is arranged between a lubricant chamber and an air chamber and the generator rotor is configured to rotate about a rotational axis, wherein the seal is arranged at an end of the stationary member. The seal includes a first lip configured to contact the generator rotor and the first lip is configured to allow a leakage of lubricant at the contact between the first lip and the generator rotor. The seal further includes a second lip arranged radially outwards with respect of the first lip and the rotational axis.
