Abstract
A method for detecting when a rotor blade of a wind turbine is stuck is described. The method can include monitoring, via a controller, a speed of rotation of the wind turbine, and, determining, via the controller, a running average of the speed of rotation. The method further includes applying, via the controller, at least one filtering operation to the running average to obtain a filtered value, and, determining, via the controller, a stuck condition of one or more rotor blades of the wind turbine based on the filtered value. The method can also include performing a control operation to reduce loading on the wind turbine based on the stuck condition.
