1. A method for stabilizing an electricity distribution network, in which an electricity generating installation is connected to the electricity distribution network and feeds electrical power into the electricity distribution network via a converter comprising:

  • detecting a network fault in the electricity distribution network;

    activating a stabilization regulator in the electricity generating installation configured to regulate the voltage of the electrical power as a function of a fed-back voltage signal and whose step-function response is configured to rise over time;

    checking whether the voltage has stabilized when a predetermined time period has elapsed since activation of the stabilization regulator; and

    increasing a reactive current feed beyond a limit which is provided for normal operation if the voltage has not yet stabilized.
