The invention relates to a method for operating a wind turbine, wherein the wind turbine is connected to an electrical supply network, and in operation, in other words when there is wind that lies above the initial speed and below the switch-off speed, electrical energy is fed into the supply network at the voltage and frequency desired or required by the supply network, wherein in operation of the wind turbine above the rated value or below the switch-off speed, the rotor of the wind turbine, which comprises at least one rotor blade, rotates, and a generator is connected to the rotor of the wind turbine, which generator is driven by the rotor in order to thus generate electrical energy, wherein the wind turbine comprises means to measure the frequency predominant in the electrical supply network, and said means for measuring the network frequency are connected to a control device for controlling the operation of the wind turbine. According to the invention, the power output by the generator of the wind turbine to the network is raised above the present power of the wind turbine briefly and for a short period of time if the network frequency of the electrical network lies below the desired target frequency of the network by a predetermined frequency value. |
