The Molas B300 Doppler wind LiDAR was developed by Movelaser, based on all-fiber coherent doppler effect, through the 4-beam VAD scanning vector synthesis technology, can measure wind speed and direction in 30-300 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 by DNV-GL (Type specification classification test and independent performance test), WINDGUARD and DTU. Molas B300 onshore wind LiDAR can be applied for onshore and offshore Wind Resource Assessment (WRA), Power Curve Validation (PCV), 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.

Certification and Calibration Reports of Molas B300 Doppler Wind LiDAR

DNV-GL Type Specific Classification For Molas B300 Doppler wind LiDAR Systems

DNV-GL has conducted an independent classification assessment of three lidar units of type MOLAS B300 doppler wind LiDAR according to the IEC 61400-12-1 Ed. 2 [4].

The classification measurement campaigns took place over two sites, with one Lidar deployed at two different sites and another lidar deployed at one site, so a total of three separate campaigns were analysed. DNV was responsible for conducting all three classfication campaigns. The first and the second classification campaigns took place at the Hamburg and Janneby test site to classify the unit MOLAS B300-117 [1] [2]. The third classification campaign took place also in Hamburg to classify the second unit MOLAS B300-202 [3].

In the report, a summary of all classification task assessments of the type MOLAS B300 lidar are shown in the picture left, and the type-specific class and standard uncertaintity of Molas B300 are average 2.4% and 1.4% respectively.
