Product Details

Wind Iris Lidar: 10-Layer Distance Measurement for Onshore Wind Turbines

| Product introduction

Molas NL series is a nacelle wind lidar independently developed for the intelligent application scheme of wind power customers. It is a laser remote sensing wind measurement device installed on the top of the wind turbine nacelle. The lidar adopts the coherent detection system, and based on the principle of laser Doppler frequency shift, realizes the accurate measurement of 50m-200m / 400m / 750m vector wind field in front of the fan impeller.
Molas NL nacelle wind lidar system provides measurement and recording of wind field information data in front of wind turbines 50m-200m / 400m / 750m, and is connected to the main control system of wind turbines, so as to realize feedforward control, optimize load and increase power generation. It can also be applied to various automated operation scenarios such as yaw correction, power curve test, wake analysis, and intelligent field group control.

| Application scenarios

With the application and development of Doppler wind Lidar in the field of wind energy, by accurately measuring the inflow wind speed and direction, it is possible to predict the accurate wind conditions on the wind rotor surface, correct system parameters in time,realize feedforward control to reduce unit load and improve the power generation efficiency, reduce manufacturing costs and extend the service life of wind turbine, so as to achieve the ultimate goal of reducing the cost of electricity.
