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.

L'invention concerne un procédé permettant de faire fonctionner une éolienne comprenant un dispositif générateur pour l'apport d'énergie électrique à un réseau, le dispositif générateur comprenant un stator et un dispositif de commande destiné à commander le dispositif générateur, une tension du stator du dispositif générateur étant mesurée au moins au moyen d'un premier dispositif de mesure, cependant qu'un courant de réseau, fourni au réseau, est mesuré au moyen d'un second dispositif de mesure. L'invention a pour but de fournir un procédé permettant de faire fonctionner une éolienne, en vue de garantir une protection suffisante de l'éolienne, y compris en cas de fluctuations du secteur. A cet effet, l'invention est caractérisée en ce qu'une tension de réseau est déterminée, au moyen d'un modèle de réseau, au moins en fonction de la tension du stator et du courant du réseau, en ce qu'à partir de la tension de réseau déterminée
