Abstract
A method for operating a wind turbine, an associated wind turbine, and an associated wind park are provided. The wind turbine has a tower with tower loads acting thereon and an aerodynamic rotor which generates a rotor thrust. The method has a step of reducing the rotor thrust. The reduction of the rotor thrust is performed while considering the effect of the reduction of the rotor thrust on the tower loads. Thus, the reduction of the rotor thrust is avoided in cases which result in undesirable or even counter-productive effects on the tower loads.
Claims14
A method comprising:
- operating a wind turbine, wherein the wind turbine has a tower, wherein tower loads act on the tower, the wind turbine having an aerodynamic rotor configured to generate a rotor thrust,
- determining whether a reduction of the rotor thrust would reduce the tower loads, and
- in response to determining that the reduction of the rotor thrust would reduce the tower loads, reducing the rotor thrust.
A wind turbine, comprising:
- a tower, wherein tower loads act on the tower,
- an aerodynamic rotor configured to generate a rotor thrust, and a controller, wherein the wind turbine is configured to:
- operate the wind turbine,
- receive signals indicative of the rotor thrust,
- determine whether a reduction of the rotor thrust would reduce the tower loads, and
- in response to determining that the reduction of the rotor thrust would reduce the tower loads, reduce the rotor thrust.
