Abstract
A method for the operation of a wind energy plant, with a synchronous generator, a superimposition gearbox, which is connected between rotor shaft and generator shaft, and a drive unit, wherein before connecting the synchronous generator to the electric grid, the drive unit drives the synchronous generator until the same has reached its rated rotational speed.
Claims10
A method for the operation of a wind energy plant, with a synchronous generator (18), a superimposition gearbox (14), which is connected between rotor shaft (12) and generator shaft (16), and a drive unit, characterised in that before connecting the synchronous generator (18) to the electric grid, the drive unit drives the synchronous generator until the synchronous generator has reached its rated rotational speed,
- the rotor shaft is uncoupled from the generator shaft (16) via the superimposition gearbox, and
- re-coupling the rotor shaft to the generator shaft via the superimposition gearbox to transfer power to the grid after the plant has been connected to the grid.
A method for connecting a wind energy plant to the grid, comprising the steps of:
- providing a wind energy plant having a synchronous generator (18), a superimposition gearbox (14), which is connected between rotor shaft (12) and generator shall (16), and a drive unit;
- uncoupling the rotor shaft from the generator shaft via the superimposition gearbox;
- driving the synchronous generator until the synchronous generator has reached its rated rotational speed, then
- connecting the synchronous generator (18) to the electric grid, and
- coupling the rotor shaft to the generator shaft via the superimposition gearbox to transfer power to the grid after the plant has been connected to the grid.
