Abstract
Provided is a control device for controlling a wind turbine, the wind turbine including a rotor and at least one blade being rotatable mounted to the rotor. The control device includes a detecting device being configured to detect an amount of a bending moment of the blade; and a change element having an input and an output, wherein the input is configured to receive the detected amount of the bending moment of the blade and the output is configured to output a response to a differential of the detected amount of the bending moment of the blade. The control device is configured to control the wind turbine based on the response.
Claims12
A control device for controlling a wind turbine, the wind turbine comprising a rotor and at least one blade being rotatable mounted to the rotor, the control device comprising:
- a detecting device being configured to detect an amount of a bending moment of the blade;
- and
- a change element having an input and an output, wherein the input is configured to receive the detected amount of the bending moment of the blade and the output is configured to output a response to a differential of the detected amount of the bending moment of the blade;
- wherein
- the control device is configured to control the wind turbine based on the response.
8 The control device according to claim 1, wherein
- the wind turbine comprises a plurality of blades, wherein the control device is configured to control the wind turbine based on the response of the bending moment of that blade which is currently pointing up.
A method of controlling a wind turbine, the wind turbine comprising a rotor and at least one blade being rotatable mounted to the rotor, the method comprising steps of:
- detecting an amount of a bending moment of the blade;
- providing a change element having an input and an output;
- inputting the detected amount of the bending moment of the blade in the input of the change element;
- outputting a response from the output of the change element;
- and
- controlling the wind turbine based on the output response.
11 The method according to claim 1, wherein
- a rotational speed of the rotor is controlled by altering a pitch angle of the blade and/or by altering an output power of the wind turbine based on the response.
