LEICE WindHorizon - Model H200 - Lidar for Wind Turbine Control
From Nacelle Wind Lidar
The WindHorizon H200 is a compact, high-precision forward-looking Nacelle Lidar that accurately detects wind speed and direction information for any 10 distance gates from 50m to 200m directly in front of the turbine hub. It is suitable for application fields such as turbine yaw error correction, wind turbine power curve test and feedforward control to reduce fan load. It is of great significance to improve wind turbine power generation efficiency, reduce wind turbine load and failure rate, and prolong wind turbine service life. It’s certified by DNV-GL in Germany with high accuracy of wind measurement, ensuring the accuracy of wind turbine power curve measurement.
Functional Features and Advantages
- Full function: yaw, feedforward control, power curve test
- High precision: wind speed 0.1m/s, wind direction 0.5°, pass white box and black box accuracy test
- High resolution: 4Hz data refresh rate, meter range resolution
