Wind measurement Molas Cl Lidar Rental Light Detection enclosure rating
| Product introduction
Molas CL tower clearance lidar is a kind of lidar that monitors the clearance distance of blade tip in real time. When the monitored blade clearance value is close to the specified minimum clearance value,the main controller of the fan unit can take protective measures immediately,Such as deceleration, retraction, etc. The application of tower clearance lidar on the existing units can prevent tower sweeping, lifting the power limit of dangerous units and increasing power generation.The application of tower clearance lidar on the future units can reduce the blade cost and the design pressure of the units.
| Application scenarios
The laser pulse of each optical channel of MolasCL has a high repetition rate of 20kHz, so there are 20000 ranging data per second. The three optical channels can generate 60000 ranging data per second. The ranging data is transmitted to the real-time processor of the main control. The processing algorithm in the processor filters the strong light interference, rain, snow, sand, dust cloud and fog interference
