摘要： A wind turbine generator, an active damping method thereof, and a windmill tower in which vibrations of the wind turbine generator itself or the windmill tower can be reduced at low cost are provided. The acceleration due to vibrations of a nacelle is detected with an accelerometer attached to the nacelle. In an active damping unit, a pitch angle of windmill blades for generating a thrust on the windmill blades so as to cancel out the vibrations of the nacelle is calculated on the basis of the acceleration, and the pitch angle is output as a blade-pitch-angle command δθ* for damping. On the other hand, in a pitch-angle control unit, a pitch angle of the windmill blades for controlling the output to be a predetermined value is calculated, and the pitch angle is output as a blade-pitch-angle command θ* for output control. The blade-pitch-angle command δθ* for damping is combined with the blade-pitch-angle command θ* for output control using a subtracter. The pitch angle of the windmill blades is controlled on the basis of the resulting blade-pitch-angle command after combining.

摘要： The present invention provides a wind turbine generator and a blade pitch angle control method thereof in which an aerodynamic imbalance of a wind turbine rotor at the time of shutdown is further reduced, the maximum load of a wind turbine is further reduced, and the wind turbine generator can be reduced in weight and cost. The wind turbine generator includes a collective pitch angle controller 11 that produces a collective pitch angle demand that is common to blade pitch angles of wind turbine blades, an individual pitch angle producing unit 13 that produces an individual pitch angle demand inherent in each wind turbine blade, multipliers 21 to 23 that multiply the individual pitch angle demand by the individual pitch angle gain; an individual pitch angle gain producing unit 14, and adder 24 to 26 that add collective pitch angle demands to the output of the multipliers 21 to 23 and supply the same to pitch actuators 31 to 33 inherent in the wind turbine blades. When shutdown is performed, the individual pitch angle gain is adjusted such that an individual pitch angle gain is reduced gradually and reaches to zero by the individual pitch angle gain producing unit 14 after first set time.
