摘要： A method and apparatus for operating a wind energy plant with a rotor blade control, a torque control and a control unit. A power limited mode of operation presets a desired value for the fed power, which is smaller than the rated value for the plant. On a threshold rotational speed, the torque is lowered through the torque control such that the preset desired value for the power is not exceeded. The threshold rotational speed, depending on the preset desired value for the moment (Mdesired), is set to a value smaller than the rated value for the rotational speed.
