WIND TURBINE AND ROTOR BLADE WITH REDUCED LOAD FLUCTUATIONS |
摘要 |
A wind turbine includes a rotor having a number of rotor blades. At least one rotor blade has openings. The rotor blade has air-displacement elements which, in use, alternately force air out of and into the openings. A sensor is provided for detecting wind speed fluctuations. A control unit is provided for controlling the air-displacement elements depending on the wind speed fluctuations detected by the sensor. The rotor blade has an aerodynamic profile with a suction side and a pressure side. At least one opening is provided on the suction side. The control unit is designed for operating the air-displacement elements of the opening on the suction side if the sensor has detected a positive speed fluctuation. At least one opening is provided on the pressure side. The control unit is designed for operating the air-displacement element of the opening on the pressure side if the sensor has detected a negative speed fluctuation. |
