Method for operating or controlling a wind turbine and method for providing primary control power by means of wind turbines

A method for operating a generating system comprising at least one wind turbine with a rotor and an electric generator coupled to the rotor for delivering electrical power into an energy distribution system with a control device which ensures that the wind turbine operates within its operating range, comprising:

• a) operating the wind turbine in a non-throttled mode that corresponds to a best usable characteristic of the wind turbine;
• b) detecting an unpredicted change in an operating parameter of the energy distribution system;
• c) reacting to the unpredicted change by feeding a higher amount of power into the energy distribution system, the higher amount of power being greater than is permitted by wind conditions by an excessive amount, the excessive amount of power being taken from the kinetic energy of the rotor;
• and
• d) returning to the non-throttled mode after the feeding of the excessive amount of power is completed.
