Abstract
Apparatus for detecting aerodynamic conditions of a rotor blade () of a wind turbine (). An acoustic sensor () may be remotely located from the rotor blade. The sensor may be focused to monitor a portion of a blade path swept by the rotor blade to detect an aerodynamic condition such as flow separation, and may provide input to a controller () for control of a pitch of the blade effective to prevent the flow separation from developing into a full stall condition. One sensor may be focused to monitor blades of more than one wind turbine. A plurality of such sensors in a wind park may be connected to a supervisory controller () to predict the propagation of wind conditions progressing through the park.
