The invention relates to a method for operating a wind turbine, comprising a generator device for outputting electric energy to a network, the generator device having a stator, and a controller device for controlling the generator device, wherein a stator voltage of the generator device is measured at least with a first measuring apparatus, and a network power that is output to the network is measured at least with a second measuring apparatus. The object of providing a generic method for operating a wind turbine in order to ensure sufficient protection of the wind turbine even during network fluctuations is achieved in that a network voltage is determined using a network model at least as a function of the stator voltage and the network power, that the determined network voltage and a predeterminable maximum phase angle present between the stator voltage and network voltage are used to determine the maximum effective power of the wind turbine that can be output, and the output effective power is regulated as a function of the determined maximum effective power that can be output and a target effective power predetermined by the control device. |
