Abstract

The present invention provides a method (900) for determining a bending angle of a rotor blade (300) of a wind turbine system (210). The method (900) comprises a step of reading in (910) at least one acceleration signal (a1) which represents an acceleration of the rotor blade acting essentially perpendicularly with respect to a rotor plane (320). In addition, the method (900) comprises a step of determining (920) the bending angle of the rotor blade of the wind turbine using the acceleration signal.
