ABSTRACT:
A wind turbine includes an electrical stall sensor configured on a pressure surface of at least one turbine blade at a location to detect backflow in a stall condition. The stall sensor includes a flap pivotally configured on the respective pressure surface so as to be moved from a first position towards a second position by backflow over the pressure surface during a stall condition. A sensor circuit responds to movement of the flap between the first and second positions and generates a corresponding electrical signal that indicates the stall condition.
