Abstract The invention concerns a method of operating a wind power installation, wherein the wind power installation is connected to an electrical supply network and in operation, that is to say when wind prevails which is above the initial speed and below the switch-off speed, feeds electrical energy into the supply network and more specifically with the frequency and voltage desired or required by the supply network, wherein in operation of the wind power installation above the rated value or below the switch-off speed the rotor of the wind power installation that has at least one rotor blade rotates and connected to the rotor of the wind power installation is a generator driven by the rotor thereby to generate electrical energy, wherein the wind power installation has means for measuring the frequency prevailing in the electrical supply network and said means for measuring the network frequency are connected to a control device for controlling operation of the wind power installation. According to the invention it is proposed that the power delivered by the generator of the wind power installation to the network is increased quickly and for a short period above the currently prevailing power of the wind power installation if the network frequency of the electrical network is below the desired target frequency of the network by a predetermined frequency value.
