The WindHorizon is a compact and high-precision nacelle-mounted forward-looking pulsed wind lidar. It can accurately measure wind speed and direction at any of 10 configurable range gates from 50m to 400m directly in front of the wind turbine hub. Additionally, the WindHorizon series includes the H800 model, The WindHorizon Series H800 model can expand the number of distance gates to 20. which extends the detection range to 200m/400m/600m/800m.
This system is ideal for applications such as yaw error correction for wind turbines, wind turbine power curve testing, feedforward control, and load reduction. It plays a significant role in improving wind turbine power generation efficiency, reducing loads and failure rates, and extending turbine service life.
