The invention relates to a method for operating a wind turbine, comprising a tower, an azimuth adjustable nacelle arranged on the tower, and a rotor provided with at least one blade angle-adjustable rotor blade, wherein by means of at least one measuring device, tower oscillations are detected and monitored during the operation of the wind turbine, and the power operation of the wind turbine is turned off if a measurement variable, in particular a moving average, of the tower oscillations exceeds a tower oscillation limit value. The invention further relates to a wind turbine. The method according to the invention is characterized in that at least during one load operation of the wind turbine, the tower oscillation limit value is defined as at least one limit value function, which is subject to the prevailing wind speed, in particular a moving average, and/or a parameter connected to the wind speed, and in several different value ranges of the wind speed or the parameter connected thereto has different functional dependencies. |
