The present invention concerns a method of operating a wind power installation having an electrical generator drivable by a rotor for delivering electrical power to an electrical network to which the wind power installation is connected. The invention further concerns a wind power installation comprising a rotor and an electrical generator coupled to the rotor for delivering electrical power to an electrical consumer, in particular an electrical network. The object of the present invention is to eliminate the above-described problems when wind power installations are connected to the electrical network. A method of operating a wind power installation having a generator for delivering electrical power to an electrical network characterised in that the power delivered to the network by the generator is regulated or adjusted in dependence on the network frequency of the electrical network.
A method of operating a wind power installation having a generator for delivering electrical power to an electrical network characterised in that the power delivered to the network by the generator is regulated or adjusted in dependence on the network frequency of the electrical network.
A wind power installation for carrying out the method according to one of the preceding claims comprising a rotor and an electrical generator coupled to the rotor for delivering electrical power to an electrical network, characterised by a regulating device having a frequency pick-up for measuring the frequency of the electrical voltage at the network (current) and that the power delivered to the network by the generator is adjustable in dependence on the network frequency measured by the frequency pick-up.
A wind power installation according to one of the preceding claims characterised in that the mechanical power of the wind power installation is reduced by the adjustable rotor blades being set into the wind.
A wind power installation according to one of the preceding claims characterised in that the wind power installation does not deliver any electrical power to the network if the network frequency exceeds a predetermined value of its reference value, preferably 2% of its reference value.
