Nacelle Mounted Wind LiDAR
Model: TDWL-800T
The Nacelle Mounted Wind LiDAR TDWL-800T Nacelle Mounted Wind Lidar is a mature product independently developed for market needs. Based on the laser Doppler frequency shift principle, it achieves feedforward control of the wind turbine main control system through remote sensing of the incoming wind vector field. The lidar is configured with a 2-beam or 4-beam structure, measuring wind speed in the 0-50m range and wind direction in the ±180° range, with accuracy up to 0.1m/s and 0.5°. Installed on top of the wind turbine, relying on core proprietary technology, it has strong anti-interference capabilities, is unaffected by blade blockage, and can accurately measure, record, and store large-scale wind field data in front of the turbine. The effective measurement frequency reaches 4Hz. The product is small, low-cost, has good adaptability and high reliability, and can run stably in harsh environments. It is used for turbine forward-looking wind measurement and wind power forecasting. Customized services are available.
