Jiuquan Grid transmission line enters the era of drone self -inspection

On July 18th, at the 330 kV Gaoyou Line 1 Iron Tower, with Guo Yang, an employee of the Power Transmission Inspection Center of the State Grid Jiuquan Power Supply Company, pressed the "Start" key, and a drone took off from the movement of the movement and began to be autonomous. Inspection. This is the company's independent implementation of drone laser spots cloud scanning and nesting planning to realize the three -dimensional inspection of the transmission line.

Jiuquan Power Grid has large coverage area and long transmission line. In order to improve the quality and efficiency of operation and maintenance operations, the company innovatively conducts an independent inspection application of the transmission drone. Flying flights, realized drones autonomously. Combined with the visual monitoring and digital means of channels, the holographic perception of the line running status and the intelligent control of the warning alarm, which greatly improves the level of the line lean operation and maintenance.

Lidar point cloud scanning is to use the drone to carry laser radar, collect the transmission line iron tower, wire, channel and peripheral environmental data, establish a three -dimensional model, and the three -dimensional presentation of the entire channel environment. And outline. Collect data entering the system. The program automatically judges the distance between the trees and the wire, the distance between the cross and the wire, and the measurement accuracy is very high, and the relative error is centimeter level.

"After completing the point cloud scanning and nesting, through the remote distribution task, the operators flew the drone at the scene. The drone carried out independent inspection operations according to the planned aircraft track. The system, automatically generates inspection reports, has improved the efficiency and quality of inspection of the transmission line. "Guo Yang introduced.

As of now, the company has completed 12 laser spots and route planning of 110-330 kV transmission lines. More than 300 kilometers of transmission lines have achieved autonomous inspection of drones. Essence It is expected that before the end of the year, the 57 330 kV lines of the company will all realize the autonomous inspection of the drone.

In the next step, the company will continue to promote the three -dimensional inspection of the transmission line, comprehensively carry out the digital empowerment business application of transmission professional, improve the level of essential security, and help digital and intelligent transformation of power grids.
