Abstract:
1. A wind park with a plurality of wind energy plants ( 10 , 12 , 14 ), which each have one plant control, which presets a desired value for the active power to its wind energy plant, and with a park control ( 28 ), which presets a desired value for the active power to be generated for each plant control and therefore limits the active power fed by the wind park to the grid to a preset value, by shutting down a first group ( 32 ) of wind energy plants ( 14 ) and at the same time presetting a desired value for the active power to a second group ( 34 ) of wind energy plants ( 10 , 12 ), characterised in that the park control re-starts the wind energy plants of the first group again once the sum of the actual values of the active power of the wind energy plants of the second group has reached the preset desired value of the active power to be fed to the grid.
