The invention relates to a method for operating a wind turbine (10), wherein during operation the wind turbine (10) supplies power, wherein the wind turbine (10) is operated with variable rotational speed between a predetermined minimum rotational speed and a predeterminable maximum rotational speed, wherein a characteristic variable (51) of an oscillation of the wind turbine (10) or of a part of the wind turbine (10) is detected. The invention further relates to a wind turbine (10) having a tower (14) and a rotor (13), wherein a generator (26) operable with variable rotational speed is provided, wherein an open-loop or closed-loop control device (36, 50) is provided, which is designed for the open-loop control or closed-loop control of the rotational speed of the rotor (13) between a minimum rotational speed and a maximum rotational speed during a power-supplying operation of the wind turbine (10), and wherein a sensor (40) for detecting a characteristic variable (51) of an oscillation of the wind turbine (10) or of a part of the wind turbine (10) is also provided. The method according to the invention is characterised in that the minimum rotational speed is altered according to the characteristic variable (51) of the oscillation. The wind turbine according to the invention is characterised in that the minimum rotational speed is alterable or is altered according to the characteristic variable (51) of the oscillation, in particular by the open-loop or closed-loop control device (36, 50). |
