The invention relates to a method for controlling a wind power installation comprising a control device for the operational management of the wind power installation by which the acceleration of the tower is measured. The invention further relates to a wind power installation with a tower, a control device for the operational management of the wind power installation and a device for measuring the acceleration of the tower. The aim of the invention is to improve the method and the wind power installation of the above-mentioned type so that oscillations can be reliably and efficiently monitored in order to find the above-mentioned frequency range for the operation of the wind power installation. The invention further relates to a method for controlling a wind power installation, comprising a tower, a control device for the operational management of the wind power installation or parts thereof and a device for measuring the acceleration of the tower. Means are provided for detecting oscillations of the tower of the wind power installation in at least two different directions. The means for detecting the tower oscillations detect the range of oscillation and/or the absolute excursion of the tower in the upper part of the tower from its rest position. The values detected by the means for determining the tower oscillation are then processed in the control device in such a manner that the operational management of the wind power installation or parts thereof is modified when the oscillation and/or the absolute excursion of the tower exceeds a predetermined first threshold value. |
