LKNW-01 Nacelle-Mounted Wind Lidar

The LKNW-01 nacelle-mounted wind lidar performs wind measurement based on coherent Doppler detection principles. Pulse optical signals generated by the fiber laser are transmitted via the optical antenna into the target atmosphere, where they interact with atmospheric aerosol particles to produce backscattered signals carrying wind velocity information.The optical antenna receives these backscattered signals, which are then interfered with internal local oscillator light and converted into electrical signals. After signal amplification, a data acquisition card digitizes the signals; the collected data is transmitted to a processor, where proprietary signal processing algorithms deliver precise vector wind field measurements ranging from 16 m to 800 m in front of the wind turbine rotor.

Overview

The LKNW-01 nacelle-mounted wind lidar performs wind measurement based on coherent Doppler detection principles. Pulse optical signals generated by the fiber laser are transmitted via the optical antenna into the target atmosphere, where they interact with atmospheric aerosol particles to produce backscattered signals carrying wind velocity information.

The optical antenna receives these backscattered signals, which are then interfered with internal local oscillator light and converted into electrical signals. After signal amplification, a data acquisition card digitizes the signals; the collected data is transmitted to a processor, where proprietary signal processing algorithms deliver precise vector wind field measurements ranging from 16 m to 800 m in front of the wind turbine rotor.

Features

· Compact size, lightweight design, low power consumption, high system integration and simple maintenance

· Four-beam layout covering the full rotor swept area to enable 3D wind field measurement

· Intelligent wireless connectivity supporting remote intelligent control

· Extended measurement range up to 800 meters to accommodate diverse operational requirements

· Excellent anti-interference performance, robust environmental adaptability and fully automatic round-the-clock operation

Application Areas

Optimized Turbine Control

Real-time collection of upstream wind data hundreds of meters ahead of the rotor provides feed-forward control reference for turbine yaw and pitch adjustment. This reduces dynamic loads on wind turbines and improves power generation output.

Safe Operation Assurance

Continuous monitoring of extreme wind conditions around the nacelle (e.g., gusts, wind shear) triggers unit protection mechanisms, minimizing equipment failures caused by sudden wind variations and cutting operational maintenance costs.

Power Curve Verification

Captures true free-stream wind speed at hub height, eliminating measurement errors induced by wind tower-rotor height discrepancies and terrain disturbances, and boosting the accuracy of power curve test results.

Wake Flow Monitoring

Accurately measures wind speed deficits, turbulence intensity and wake diffusion range within turbine wakes, delivering core data support for wind farm layout optimization and cluster wake control strategy formulation.
