1. A method for operating a wind power plant comprising a rotor with angle-adjustable rotor blades and a generator rotationally connected thereto and having a controllable torque, said method comprising:
limiting the torque of the generator to a changeable maximum setpoint value (MSoll;Max) set by a controller of the wind power plant that is linked to the blade pitch angle of the rotor blades in such a way that the maximum setpoint value (MSoll;Max) of the torque of the generator at the switch-on blade pitch angle is less than a rated torque value (MNenn) of the generator that is present when the wind power plant is at rated power and the maximum setpoint value of the torque of the generator (MSoll;Max) at a rated blade pitch angle that differs from the switch-on blade pitch angle is equal to the rated torque value (MNenn) of the generator.
