Abstract
It is proposed a method for detecting a status of a rotor blade (20) for a wind turbine (10), the rotor blade (20) including at least an aerodynamic device (31, 32, 33, 34, 35, 36) for influencing the airflow, the aerodynamic device (31, 32, 33, 34, 35, 36) being movable between a first and a second configuration, the method comprising the steps of:
- measuring an output signal (200) measured by at least one sensor (201, 202, 203, 204) installed on the wind turbine (10),
- moving the aerodynamic device (31, 32, 33, 34, 35, 36) between the first configuration and the second configuration,
- measuring a change (210) in the output signal (200) induced by the moving of the aerodynamic device (31, 32, 33, 34, 35, 36),
- post-processing the measured output signal (200) for performing an analysis of the measured change (210) in the output signal (200),
- comparing the post-processed signal (S2) with a reference signal (S1) or parameter,
- deriving a status of the rotor blade (20) based on said step of comparing.
