The Molas B300 wind lidar which based on all-fiber coherent doppler effect，through the eight-beam VAD scanning vector synthesis technology, can measure wind speed and direction in 40-300 m above the lidar. In addition, air temperature, humidity and other parameters can be measured by the sensor module. Molas B300 has the characteristics of high precision, stable system performance, maintenance friendly and data security. It has been tested and calibrated by WINDGUARD, the world's leading wind assessment agency, and China Meteorological Administration. Molas B300 can be applied to wind resource assessment, post evaluation of wind farm, wind power prediction system, operation management of wind farm, atmospheric physics research, weather forecast, etc.
The four core modules of Molas B300, including fiber lidar emitter, laser transceiver system, high-speed data acquisition system, data processing softwareare independently developed by Movelaser. The core modules, which have a high degree of matching and ensure the unified coordination and data information security of the whole machine system, have reached international advanced level.
Molas NL is a nacelle-based wind lidar which is independently developed by Nanjing Movelaser for wind power customers' intelligent application solutions. It is a remote sensing laser device which can be installed above the wind turbine nacelle. It uses a coherent detection system based on the principle of laser Doppler frequency shift to achieve an accurate measurement of the wind vector field from the top of the nacelle to the front tens of to several hundred meters ahead of turbine rotor.
Molas NL measures and records wind data information of 400 m in front of wind turbines. After it's connected to the main control system of the wind turbine, it can realize the functions in a variety of automated operating scenarios such as yaw control, load optimization, power curve test and so on.
