摘要：
A wind turbine variable is controlled by detecting air flow conditions in front of the leading edge of the blade. One or more Laser Doppler Anemometers are mounted on or incorporated into the blade to determine air flow velocity in the region in front of the leading edge of the blade. The measured flow conditions may be used to control the position of a control surface such as a trailing edge flap or the rotor speed. The LDAs may comprise lasers of different frequencies to enable more than one component of flow velocity to be measured.
