A method for controlling a wind power installation having a rotor operated with variable speed and having rotor blades that are adjustable in their blade angle. The installation is controlled in a partial-load range by an open-loop operating-characteristic control, which uses an operating characteristic. The operating characteristic presets a relationship between the rotational speed and a generator state variable to be set that is a generator power or torque. A value of the generator state variable preset by the operating characteristic is set in dependence on a detected speed. The installation is controlled in a full-load range by a closed-loop pitch control, in which the rotational speed is controlled to a speed setpoint value by adjusting the blade angles. In a presettable range of the partial-load range and/or in a transitional range from the partial-load range to the full-load range, the installation is controlled by a speed-power control.
