Abstract
A method for operating a wind turbine (). The wind turbine () is operated with variable rotational speed between predeterminable minimum and maximum rotational speeds. A characteristic variable () of an oscillation of the wind turbine () is detected. The wind turbine () includes a tower () and a rotor (). An open-loop or closed-loop control device () provides open-loop control or closed-loop control of the rotational speed of the rotor () between a minimum rotational speed and a maximum rotational speed during a power-supplying operation of the wind turbine. A sensor () detects a characteristic variable () of an oscillation of the wind turbine () and the minimum rotational speed is changed depending on the characteristic value () of the oscillation. The minimum rotational speed is altered depending on the characteristic variable () of the oscillation by the open-loop or closed-loop control device ().
