MolasCL: Preventing Tower Sweeping and Increasing Power Generation with Tower Clearance Lidar
| 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
In order to meet the specialized needs of wind turbine tower clearance monitoring and improve the practical application in this specific field
Usability, data reliability, and environmental adaptability, MolasCL is equipped with three beam ranging and a set of dedicated computers
Method, including filtering out strong light (sunlight) interference, filtering out rain, snow, sand and dust interference, identifying fog interference, andThick fog recognition and other functions, combined with the high repetition rate advantage of MolasCL laser pulses and its high-performance computing platform .
The advantages of high-throughput data processing can greatly improve data efficiency, reduce false alarm rates, and maintain high accuracy
Timeliness helps the wind turbine control to react quickly and avoid affecting power generation due to false alarms, making it more effective than
Ordinary ranging radar has incomparable advantages
