Beschreibung
Zusammenfassung:	The invention refers to a wind turbine control system and method, for the type of wind turbines comprising a rotor, an asynchronous generator driven by the rotor and configured for providing an active power to a grid, and a power converter (3) connected to the generator and configured to interact with said generator for generating the required active power for the grid. The control system comprises a converter control unit (4) for controlling the power converter (3) and for estimating a frequency derivative (Fd) of the frequency (F) of the grid, and a wind turbine controller (5) configured for receiving said estimated frequency derivative (Fd) and for considering said received frequency derivative (Fd) for determining a synthetic inertia. The converter control unit (4) controls the power converter (3) to cause the generator to also provide the synthetic inertia, in the form of active power.
