Wind Energy Site Monitoring — Anemometer, Wind Speed and Direction Sensor

Wind Energy Site Monitoring — Anemometer, Wind Speed and Direction Sensor 

NiuBoL High-Precision Wind Speed and Direction Monitoring · Full-Process Digital Management of Wind Farms 

I. Solution Background

Wind energy is a vital component of clean energy. The efficiency and safety of wind farms depend directly on accurate wind resource assessment and real-time monitoring. Traditional wind farms face the following challenges: 

- Large errors in wind resource assessment: Mechanical anemometers have low accuracy and are susceptible to wind-blown sand and low temperatures, leading to biased investment decisions.

- Insufficient optimization of turbine operation: Delayed real-time wind speed and direction monitoring results in untimely nacelle yaw adjustments and reduced power generation efficiency.

- High risks from extreme weather: Lack of intelligent early warning and resistance to harsh environments can easily cause equipment damage and personnel safety hazards.

- Fragmented data: Wind speed, direction, environmental, and turbine vibration data are stored in isolation, resulting in low operational and maintenance (O&M) efficiency. 

To address these issues, the NiuBoL Wind Energy Site Monitoring Comprehensive Solution adopts a full-chain approach of “high-precision sensors + edge collectors + cloud platform + mobile management”, enabling refined control of wind farms from site selection and assessment to daily O&M.
