Filtering out interference, high repetition rate laser pulses, effective detection range of 300 meters

| Product introduction

The clearance of the wind turbine tower is the closest distance between the blade tip of the unit and the tower wall at the height of the blade tip. With the development of wind turbine technology and the improvement of energy efficiency requirements, wind turbine blades are becoming longer and more flexible. At the same time, due to the complex geographical environment and wind conditions of wind turbine locations, or due to complex meteorological conditions such as cold currents and typhoons, wind turbine blades have the risk of tower sweeping. After tower sweeping, the blades may be replaced, or in severe cases, the entire unit may be scrapped, which will bring huge economic and property losses.

| 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

| Product Features

MolasCL can only be used for clearance measurement in engine room installation, and can be installed at any position inside or below the fan hood by opening holes Thread the laser beam out of the cabin cover or install it outside the cabin cover. Through the calibration process, the radar laser beam forms an inclination angle towards the impeller surface, causing excitation
The beam of light is located at the lowest point of the impeller (blade tip height) at the desired monitoring clearance point. When the blade is running, bending towards the tower side, or touching the beam of light, the radar will The radial distance between the blades can be measured, and the clearance value can be calculated using a certain inversion algorithm.
