    摘要: Apparatus for detecting aerodynamic conditions of a rotor blade (22) of a wind turbine (10). An acoustic sensor (24) 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 (27) 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 (120) to predict the propagation of wind conditions progressing through the park.

    摘要: A method is proposed for operating a wind turbine (140) during idling, comprising a rotor hub, thereby controlling a rotational speed of the rotor hub during idling of the wind turbine (140) based on a determined rotational speed (150) of the rotor hub.
    Further a wind turbine, a control device and a computer program product are suggested.
