AI Technical Summary
Technical Problem
Wind turbines experience structural damage due to torsional vibrations of rotor blades, which can be exacerbated by stalling or icing, leading to increased loads on other components and reduced lifespan.
Method used
A method for operating wind turbines that detects torsional vibrations exceeding a threshold, generating output signals to adjust the turbine's operation, such as changing pitch angles or reducing electrical power output, to mitigate these vibrations and prevent damage.
Benefits of technology
The method effectively reduces torsional vibrations, thereby extending the lifespan of rotor blades and other wind turbine components by implementing real-time adjustments based on sensor data from pitch angle, torsional bending moment, and angular acceleration measurements.

Abstract
According to an embodiment, the method is for operating a wind turbine (100) having a rotor (10) with at least one rotor blade (1, 2, 3) and a setting system (31, 32) which is configured to change the operation of the wind turbine. The method comprises a step in which first trigger information (Ia1) is provided, wherein the first trigger information is representative of whether the torsional movement of at least one rotor blade exceeds a threshold. If this is the case, a first output signal (OS1) is generated which is configured to cause the setting system to change the operation of the wind turbine in order to reduce the torsional movement of the at least one rotor blade.
