WindHorizon H400

Forward-looking Nacelle Lidar

Product Description

The WindHorizon H400 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 400m directly in front of the fan hub.

It is suitable for application fields such as fan 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.

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

Wide range of adaptable models: Customized development for different models (including detection distance, optical opening angle, data output, etc.)

Easy installation: small size, light weight, low power consumption, fast installation, support for multiple compatibility data interfaces

Automatic unattended observation: remote networked data acquisition and device monitoring

Strong robustness: continuous and stable operation in harsh environments on land and at sea
