Abstract: A method for the operation of a wind energy plant with a double-fed asynchronous generator which has a mode of operation as a phase shifter, in which reactive power is fed into the electric power supply grid, the method having the following steps: the stator of the asynchronous generator is short-circuited, the asynchronous generator is run-up to a predetermined rotational speed from a working rotational speed range via a converter after running up, the short-circuit in the stator is cancelled, the double-fed asynchronous generator is synchronized with the electric power supply grid, and it is driven for the generation of reactive power.
