Beschreibung
Zusammenfassung:	A wind turbine includes a tower, an aerodynamic rotor operable at a variable rotor speed and having a plurality of rotor blades each having an adjustable rotor blade setting angle and a generator for generating an electrical output power. An operating characteristic curve is prespecified for operating the wind turbine. The operating characteristic curve indicates a relationship between the rotor speed and the output power. A controller is provided, which sets the output power in accordance with the operating characteristic curve depending on the rotor speed. The the operating characteristic curve has a starting rotation speed to which the rotor speed increases as soon as the wind turbine starts when a sufficient wind speed is reached. The starting rotation speed is defined depending on a tower natural frequency of the wind turbine and/or depending on a detected turbulence measure of the prevailing wind.
