A method of handling a wind turbine is provided including a nacelle coupled via a yawing system to a tower for protection against high wind load, the method including: supplying a control signal to a yawing actuator of the yawing system, while the nacelle is in a first orientation; exerting, by the yawing actuator, a torque to the nacelle relative to the tower, thereby turning the nacelle to a second orientation being a downwind orientation.

Handling a wind turbine in a severe weather condition

A wind turbine is provided including: i) a tower, ii) a nacelle coupled to the tower, iii) a yaw system arranged between the tower and the nacelle and configured to move the nacelle with respect to the tower, iv) an orientation determination device, configured to detect a current relative orientation between the nacelle and the wind direction to obtain an alignment parameter, v) a wind parameter determination device, configured to detect a current wind parameter to obtain a wind parameter, and vi) a control system being configured to: a) receive the alignment parameter and the wind parameter to obtain a load criterion, b) provide a maximum load criterion based on a maximum misalignment criterion that is different for at least two different wind parameters, c) determine, if the load criterion fulfills the maximum load criterion, and d) control the yaw system based on the determination result.
