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.
