Abstract
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.
Claims15
A method of handling a wind turbine comprising a nacelle coupled via a yawing system to a tower, the method comprising:
- supplying a control signal to a yawing actuator of the yawing system, while the nacelle is in a first orientation;
- and
- 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,
- wherein the second orientation is defined with respect to an actual wind direction measured by one or more wind direction sensors or with respect to the first orientation,
- wherein a definition of the second orientation is switched during the turning of the nacelle as a result of the torque exerted by the yawing actuator, depending on an availability of a wind direction signal provided by the one or more wind direction sensors.
An arrangement for handling a wind turbine comprising a nacelle coupled via a yawing system to a tower for protection against high wind load, the arrangement comprising:
- a control signal generator configured:
- to supply a control signal to a yawing actuator of the yawing system, while the nacelle is in a first orientation;
- to cause the yawing actuator to exert a torque to the nacelle relative to the tower, thereby turning the nacelle to a second orientation being a downwind orientation,
- wherein the second orientation is defined with respect to an actual wind direction measured by one or more wind direction sensors or with respect to the first orientation,
- wherein a definition of the second orientation is switched during the turning of the nacelle as a result of the torque exerted by the yawing actuator, depending on an availability of a wind direction signals from the one or more wind direction sensors.
