1. control a method for the rotating speed of rotor, this rotor has at least one rotor blade, rotor shaft and the generator being connected with this rotor, and described method comprises:

  • By controlling the torque of described generator, with the torque to described rotor shaft, control;

    AndBy a plurality of continuous steps, change the inclination angle of described at least one rotor blade and maintain the inclination angle of described at least one rotor blade substantially constant between conversion, to helpThe rotating speed that maintains described rotor when the wind-force speed changing is greater than predetermined wind speed is substantially constant;

    The adjustment yardstick of wherein one or more steps is different from or is same as the yardstick of other one or more steps adjustment.
