Innovative application of drones for automatic inspection Chongzuo Power Supply Bureau escorts the power grid to prepare for summer peak

On August 7, China News Service’s Guangxi News reported that the double-high sugarcane in Chongzuo area was growing gratifyingly in midsummer. On August 6, after a heavy rain, a drone took off from the Qinghe substation and conducted flight inspections along the distribution lines beside the sugarcane fields. The drone transmits the lush scenery and inspection footage to the drone automatic inspection platform located 35 kilometers away from the production command center of Guangxi Chongzuo Power Supply Bureau of China Southern Power Grid

Since this year, Chongzuo Power Supply Bureau has adopted innovative transmission, transformation and distribution drone integrated collaborative inspection technology to comprehensively promote "UAV full-service inspection smart nest" in the network area to achieve transmission, transformation, Equipped with "Trinity" UAV full-service comprehensive inspection. During the peak summer season, the bureau regularly uses "Smart Machine Nest" remote-controlled drones to conduct inspections of heavy-load substations and lines, providing smarter, more accurate and more efficient maintenance for local residents' production and life. Electrical service

Chongzuo Power Supply Bureau has completed 39 220 kV transmission lines, 67 110 kV transmission lines, 271 35 kV transmission lines, 10 220 kV substations, 33 110 kV substations, 103 35 Grid equipment data collection and modeling work for kilovolt substations and 11,019 kilometers of 10 kilovolt distribution lines

Since the first autonomous drone inspection in May 2022 to July 30 this year, the agency has completed a total of 15,675 flight missions, taken 340,400 equipment photos, and discovered a total of 3,052 defects and 8,844 hidden dangers. , compared with traditional manual inspection, time is saved by 93%. After the inspection, 29 urgent and major defects have been eliminated, and 6,187 serious hidden dangers have been dealt with, with a handling rate of 64.1%. Compared with before using Machine Nest, the discovery rate of hidden dangers and defects has increased by about 20%, and the processing rate of serious hidden dangers has increased by 10.4%, ensuring comprehensive coverage and no blind spots of hidden danger investigation and management

In the next step, Chongzuo Power Supply Bureau will further improve the application of "smart machine nest" technology and explore methods such as grid inspection, multiple machines in one nest, and near-nest linkage to replace individual drone inspections. This will further improve inspection efficiency, which is expected to increase by 60%-70%. This will provide stable and high-quality power contribution to the construction of Chongzuo Area of ​​Guangxi Free Trade Zone. (over)
