The invention relates to a method for operating at least one first wind turbine (31), having the following steps: - detecting a tower vibration and - introducing a procedure for reducing the vibration if the detected tower vibration is or contains a longitudinal vibration (40) and if the amplitude of the longitudinal vibration (40) exceeds a specified threshold, wherein the procedure for reducing the vibration includes the following steps: - holding the current pitch angle at the current value for a specified holding time period, - changing the pitch control algorithm being used, in particular such that the control speed is reduced, - adjusting the azimuth position by a specified azimuth angle, - switching the operation of the first wind turbine (31) from a first operating mode based on a first power characteristic to a second operating mode based on a second power characteristic, and/or - if the first wind turbine (31) is arranged behind a second wind turbine (32) in a wind park (34) with respect to the current wind direction, matching the rotational speed of the first wind turbine (31) to the rotational speed of the second wind turbine (32) such that the rotational speed of the first wind turbine (31) deviates from the rotational speed of the second wind turbine (32) at least by a specified differential rotational speed. |
