Abstract

The rotor blades of a wind turbine each have a plurality of fibre optic pressure variation sensors which can detect the onset of a stall condition. The output of the stall condition sensors is input to a stall count circuit which increases a stall count signal each time a stall indication is received. The stall count signal is decayed exponentially over time and the current signal is summed with the decayed signal from a previous sampling period to form a value from which a stall margin is determined. An ?:? curve of tip speed to wind speed ratio ? against pitch angle reference ? is then determined from the stall margin.
