Abstract
A method for operating a wind turbine is provided. The wind turbine has a tower with external tower loads acting thereon and has an aerodynamic rotor with rotor blades having adjustable pitch angles, which rotor generates rotor thrust. The method comprises the following steps: determining a speed of a tower head of the tower and/or of a nacelle of the wind turbine, determining an absolute wind speed in the region of the wind turbine, determining a pure wind power on the rotor on the basis of the absolute wind speed, determining an apparent wind power on the rotor on the basis of the speed of the tower head and/or of the nacelle, determining an aerodynamic tower vibration power on the basis of a difference between the apparent wind power and the pure wind power, and performing feedback control of the wind turbine using the aerodynamic tower vibration power.
