Abstract
A method of controlling a wind turbine, wherein the wind turbine includes a hub having at least one blade with at least one an add-on member which is actuated to alter aerodynamic properties of the blade. The method includes a step of acquiring a target noise level, and a step of controlling the at least one add-on member of the blade such that an actual noise level caused by the operation of the wind turbine is equal to or below the target noise level.
Claims14
A method of controlling a wind turbine, the wind turbine comprising a hub having at least one blade comprising at least one first add-on member and at least one second add-on member, wherein the at least one first add-on member is closer to an inboard portion of the blade than the at least one second add-on member, the at least one first add-on member and the at least one second add-on member being actuated to alter aerodynamic properties of the blade, the method comprising:
- acquiring a target noise level;
- and
- controlling the at least one add-on member of the blade such that an actual noise level caused by the operation of the wind turbine is equal to or below the target noise level;
- wherein the first add-on member is controlled in a different manner compared with the second add-on member, the first add-on member being controlled to achieve a first noise reduction level and the second add-on member is controlled to achieve a second noise reduction level, further wherein first noise reduction level is lower than the second noise reduction level.
A control device for controlling a wind turbine, the wind turbine comprising a hub having at least one blade with at least one an add-on member which is actuated to alter aerodynamic properties of the blade, wherein
- the control device is configured to acquire a target noise level;
- and
- the control device is configured to control the at least one add-on member of the blade such that an actual noise level caused by the operation of the wind turbine is equal to or below the target noise level;
- wherein
- the control device is configured to control the at least one add-on member such that a power generation of the wind turbine is maximum, while the actual noise level caused by the operation of the wind turbine is maintained equal to or below the target noise level.
