A method for operating a wind power installation which is connected to a network connection point of an electrical supply network and is intended to produce and feed electrical energy into the electrical supply network, wherein the electrical supply network has a network nominal frequency and is operated at a network frequency, and the wind power installation which comprises an electrical generator with a generator nominal power can be regulated on the basis of the network frequency, comprising the steps of: using the electrical generator to produce an electrical generator power for feeding into the electrical supply network, feeding the electrical generator power or a part of it into the electrical supply network as electrical feed-in power on the basis of the network frequency, wherein, in a first supporting stage, the electrical generator power is reduced on the basis of the network frequency in order to accordingly reduce the electrical feed-in power, and, in a second supporting stage, the electrical feed-in power is reduced such that the electrical feed-in power is less than the electrical generator power.
A method for operating a wind power installation that is connected to a network connection point of an electrical supply network, wherein the wind power installation is configured to produce and feed provide electrical energy into the electrical supply network, wherein the electrical supply network has a network nominal frequency and is operated at a network frequency, and wherein the wind power installation comprises an electrical generator with a generator nominal power, wherein the electrical generator is configured to can be regulated based on the network frequency, the method comprising:
The method as claimed in claim 14, wherein the switching device for converting electrical power into thermal power is set up to convert electrical power corresponding to the generator nominal power into thermal power for at least three seconds.
A method for operating a wind power installation that is connected to a network connection point of an electrical supply network, wherein the electrical supply network has a network nominal frequency and is operated at a network frequency, and wherein the wind power installation comprises an electrical generator with a generator nominal power, wherein the electrical generator is configured to be regulated based on the network frequency, the method comprising:
