Molas NL Offshore Wind Lidar for Wind Speed & Direction Measurement with IP67 Protection


| 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

For fan testing, such as blade load analysis, power curve testing, wake analysis, etc.
