Abstract

The invention relates to a method for detecting a torsion instability of a rotor blade of a wind power plant. The method comprises the measurement of an acceleration with a fiber-optic acceleration sensor, the acceleration sensor being provided at a radial position in the region of the outer 70 % of the radius of the rotor blade, and the evaluation of the acceleration for generating a signal for detecting a torsion instability, in particular flutter, and/or a signal for detecting a torsional/bending coupling.
