method for supplying electrical power to an electrical distribution grid, wind power installation, and wind farm

摘要

The invention relates to a method of providing electrical power to an electrical distribution network by means of at least one wind power installation at a network connection point, wherein the at least one wind power installation comprises an aerodynamic rotor with rotor blades and the rotor has a moment of inertia and can be operated at a variable rotor speed, at least one wind power installation comprises a generator for generating a generator output, multiple power generators supply power to the distribution grid Electricity and multiple consumers draw power from the power grid so that a power balance between the power supplied and the power extracted is produced in the power grid, which is positive when more power is being supplied than is removed. The method comprises the following steps: providing a basic amount of electrical power according to the amount of wind power available; specify an auxiliary power to be additionally supplied and additionally supply the specified amount of auxiliary power to be additionally supplied in order to assist the mains, where an amount of available auxiliary power for the auxiliary power to be supplied is determined and the Auxiliary power to be supplied additionally is specified according to the determined amount of available auxiliary power.
