Resumen de: EP4563815A1
There is described a method for operating a wind turbine, a safety system, and a wind turbine comprising a rotor, at least two pitchable rotor blades, a pitching system, an operation controller and a safety controller. The method comprising the steps of: determine a value for at least one safety paremeters with the safety controller, compare the value of the at least one safety parameters with at least one safety threshold and if the value is different from the at least one safety threshold the safety controller delivers a warning signal to the operation controller and prevents the wind turbine (100) from starting up. Further, a safety system comprising a memory and a processor and means for carrying out the method is also disclosed.
