Wind Turbine Acoustic Radar

This wind turbine acoustic radar is a dedicated acoustic meteorological measuring device customized for wind farm operation and wind resource assessment. Based on the acoustic Doppler echo principle, it continuously monitors horizontal wind speed, wind direction and vertical airflow fluctuations at heights ranging from 10 m to 200 m above ground. It supplies real-time, uninterrupted vertical wind profile data, forming reliable low-altitude wind field support for wind power meteorological guarantee, turbine safety operation and wind resource evaluation.

Built on the acoustic Doppler wind measurement principle tailored for wind power, this radar transmits acoustic pulses to compute wind parameters via echo frequency shifts from atmospheric turbulence without radio spectrum approval and delivers round-the-clock stable wind profile data dedicated to wind farms; it covers the critical 10–200 m rotor sweep height matching turbine blades, precisely detecting wind shear, vertical airflow shifts and low-level jets that threaten unit safety and power output, which conventional meteorological towers cannot continuously monitor layer by layer long-term. Its built-in algorithms run nonstop data analysis to output real-time wind parameter changes for turbine risk warning and smart scheduling, while the low-noise acoustic transceiver design allows deployment near wind turbines, construction sites and villages without noise complaints. The compact, lightweight all-in-one unit can be quickly assembled and debugged, fitting both permanent monitoring stations and temporary mountain or coastal wind resource survey sites.

It is widely used in wind farm wind resource survey and site selection, wind turbine real-time safety monitoring, airport flight safety monitoring, daily weather forecasting, offshore marine meteorological research, environmental impact assessment, and meteorological guarantee for large-scale events.

This acoustic wind measuring device adopts sound wave detection, eliminating radio spectrum application procedures and resisting electromagnetic interference generated by wind turbine generators and converter cabinets. It focuses on the critical 10–200 m blade sweeping layer, providing complete continuous vertical wind field data to support accurate wind resource evaluation and scientific turbine layout planning. It avoids high construction and maintenance costs of fixed meteorological towers, and removes repeated weather balloon consumption, significantly reducing long-term operation labor and material costs. Acoustic measurement is barely affected by fog, light rain and low visibility, maintaining stable data output under harsh weather where optical wind measurement equipment fails. Low-noise operation allows unrestricted installation in wind farm core areas and adjacent residential zones. Lightweight design enables fast mobile deployment, allowing users to launch low-altitude wind field measurement at any wind resource survey location efficiently.
