ABSTRACT:
A method for operating a wind turbine during a loss of communication is described that includes coupling a pitch controller to at least one wind turbine blade and to a wind turbine controller, establishing communication between the pitch controller and the wind turbine controller, and detecting a loss of communication between the pitch controller and the wind turbine controller. After a loss of communication is detected, the method further includes waiting for a first predetermined amount of time to elapse, independently pitching the at least one wind turbine blade to a predetermined position, waiting for a second predetermined amount of time to elapse, and maintaining the at least one wind turbine blade in the predetermined position until a rotation of the at least one wind turbine blade stops.
