A wind park with a plurality of wind energy plants, 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, which presets a desired value for the active power to be generated for each plant control and limits the active power fed by the wind park to a preset value, by shutting down a first group of wind energy plants and presetting a desired value for the active power to a second group of wind energy plants at a time, characterised in that the park control starts the wind energy plants of the first group again when 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 and/or a predetermined time duration has elapsed.

Wind park and method for the operation of a wind park

A method for a functional test of a wind turbine generator plant which comprises the following procedural steps: a control unit for the wind turbine generator plant reads in actual values from at least one structural part of the wind turbine generator plant and generates control signals for actuators of the wind turbine generator plant, a simulation unit has at least one input and at least one output as well as one or more mathematical models which depict the behaviour of one or more structural parts of the wind turbine generator plant, the control signals are applied to the input of the simulation unit and the modeled actual values of the models on the structural parts are applied to the output of the simulation unit, wherein the actual values of the simulation unit are applied to the input of the control unit and the control signals of the control unit are applied to the input of the simulation unit; the simulation unit models the actual values of the structural parts resulting for the control signals applied, for certain initial conditions.
