The invention involves a wind turbine comprising at least one blade (5) in turn comprising a blade body (501), lift-regulating means (502) adapted for movement in relation to the blade body (501) so as to regulate the lift of the blade, and load sensing means (5022, 506) for determining a load acting on the lift-regulating means (502), the wind turbine further comprising an actuation control unit (6) adapted to control the movement of the lift-regulating means (502) based on output from the load sensing means (5022, 506). In addition to output from the load sensing means (5022, 506), the actuation control unit (6) is adapted to control the movement of the lift-regulating means (502) based on the movement of the lift-regulating means (502).
A wind turbine comprising at least one blade in turn comprising a blade body, a lift regulator adapted for movement in relation to the blade body so as to regulate the lift of the blade, and a load sensor for determining a load acting on the lift regulator, the wind turbine further comprising an actuation control unit adapted to control the movement of the lift regulator based on output from the load sensor, wherein in addition to output from the load sensor, the actuation control unit is adapted to control the movement of the lift regulator based on the movement of the lift regulator.
A wind turbine comprising at least one blade in turn comprising a blade body, and a lift regulator adapted for movement in relation to the blade body so as to regulate the lift of the blade and comprising an actuator adapted to effect the movement of the lift regulator, the blade further comprising a load sensor for determining a load acting on the lift regulator, the wind turbine further comprising an actuation control unit adapted to control the movement of the lift regulator via the actuator based on output from the load sensor, wherein the actuator comprises an electric motor in turn comprising the load sensor.
A method for controlling a wind turbine comprising at least one blade in turn comprising a blade body and a lift regulator adapted for movement in relation to the blade body so as to regulate the lift of the blade, the method comprising determining a load acting on the lift regulator, and controlling the movement of the lift regulator based on the load acting on the lift regulator, wherein controlling the movement of the lift regulator is also based on the movement of the lift regulator.
