Resumen de: EP4671530A1

According to an embodiment, the method is for operating a wind turbine (100) having a rotor (10) with at least two rotor blades (1, 2, 3) and a pitch adjustment system (500) for adjusting the pitch angles (β_1) of the at least two rotor blades. The method comprises a step of determining first information (11) which is representative of the appearance of a failure in the pitch adjustment system while the rotor is rotating. In a further step, second information (12) is provided which is representative of the actual rotational speed (n_a) of the rotor. Then, third information (13) is determined depending on the first and the second information, wherein the third information is representative of a pitch angle setpoint (SP_β_i) for at least one rotor blade. The pitch angle setpoint depends on the actual rotational speed and is chosen to reduce the rotational speed of the rotor. When the wind turbine is operated according to the third information, a pitch angle of at least one rotor blade is adjusted to the pitch angle setpoint.
