Abstract
A method (200) for controlling a wind turbine (100) with a rotor having at least one rotor blade (17), the method comprising: measuring (210) a strain of the at least one rotor blade; changing (220) a pitch angle of the at least one rotor blade based at least partially on the measured strain of the at least one rotor blade; whereby the measurement of the strain of the at least one rotor blade measures at least one strain in the area of a blade root of the rotor blade (17).
Claims20
A method for controlling a wind turbine with a rotor having at least one rotor blade, the method comprising:
- measuring, with a sensor, a strain of the at least one rotor blade;
- changing a pitch angle of the at least one rotor blade based at least partially on the measured strain of the at least one rotor blade;
- whereby the measuring of the strain of the at least one rotor blade measures at least one strain in an area of a blade root of the at least one rotor blade.
A wind turbine comprising:
- a rotor including at least one rotor blade;
- a fiber-optic strain sensor configured for measuring a strain between a first point and a second point, remote from the first point, of the at least one rotor blade of the wind turbine;
- and
- a control unit configured to change a pitch angle of the at least one rotor blade, based at least partially on a strain of the at least one rotor blade as measured by the sensor;
- wherein the sensor configured as a fiber-optic strain sensor arranged in a blade root of the at least one rotor blade.
