Abstract: A wind energy installation having a wind rotor, a generator which is driven thereby and interacts with a converter in order to produce electrical power, rotation-speed regulation and converter control which interacts therewith, wherein the rotation-speed regulation outputs a nominal rotation speed signal (nref). Furthermore, additional regulation is provided, which has an input for an additional power and is designed to produce a rotation speed change signal therefrom, taking account of a rotator inertia moment, and to output this as an output signal, which is added to the nominal rotation speed signal via a logic element. Kinetic energy is taken from the wind rotor in a controlled manner by reducing the rotation speed and is converted by the generator to additional electrical energy. This allows primary regulation power to be made available deliberately by rotation speed variation, to be precise even in unsteady wind conditions.
