SYSTEM OG FREMGANGSMÅDE TIL OVERVÅGNING AF ROTORBLADTILSTAND AF VINDMØLLER

A method (400) for detecting when a rotor blade (22) of a wind turbine (10) is stuck is described. The method (400) can include monitoring (402), via a controller (26), a speed of rotation of the wind turbine (10), and, determining (404), via the controller (26), a running average of the speed of ro...

Zusammenfassung:	A method (400) for detecting when a rotor blade (22) of a wind turbine (10) is stuck is described. The method (400) can include monitoring (402), via a controller (26), a speed of rotation of the wind turbine (10), and, determining (404), via the controller (26), a running average of the speed of rotation. The method (400) further includes applying (406), via the controller (26), at least one filtering operation to the running average to obtain a filtered value, and, determining (408), via the controller (26), a stuck condition of one or more rotor blades (22) of the wind turbine (10) based on the filtered value. The method (400) can also include performing (410) a control operation to reduce loading on the wind turbine (10) based on the stuck condition.
