China News Service, Taiyuan, April 5 (Gao Yuqing) A reporter learned from the State Grid Shanxi Electric Power Company on the 5th that recently, the Shuozhou Shentou switching station in Shanxi-Yantong double-circuit line was reconnected to the Shanxi 1,000 kV substation At the 500 kV line project site, Shanxi's 500 kV and above transmission line projects used drone AI for independent acceptance for the first time.
It is understood that this project is one of a series of projects to adjust the "West-to-East Electricity Transmission" channel in Shanxi. According to the milestone plan, the project will be put into operation at the end of April 2024, and the "West-to-East Power Transmission" channel adjustment series projects will be fully put into operation in June. By then, the "two horizontal" ultra-high voltage transmission capabilities will be fully utilized to alleviate the power shortage in the Beijing-Tianjin-Hebei region, promote the consumption and transmission of new energy in northern Shanxi, and drive the sustainable economic development of Shanxi Province. At the same time, we will improve the reliability of power supply and further realize the safety and stability of Shanxi Power Grid's 500 kV grid and North China UHV ring grid.

"Traditional quality acceptance is mainly based on manual tower inspection and ground instrument measurement. It is easily affected by terrain, weather, measurement angle, etc., and has visual blind spots, which affects the acceptance effect." Wang Bo, relevant person in charge of the State Grid Shanxi Construction Branch According to the introduction, this innovative acceptance uses drone RTK + front-end AI visual navigation, automatic target tracking and locking, adaptive zoom shooting and other technologies. Compared with traditional RTK flight shooting, this innovative acceptance has the full automatic shooting of key parts and a 10-fold increase in pixels. Advantages include the above and automatic data classification management after the job is completed. The data formed by AI automatic acceptance can provide data processing personnel with an immersive sensory experience and make it easier to detect minor defects.

This drone inspection captured the real-time installation status of transmission line towers, fittings, insulator strings and other parts, and accurately scanned the distance between ground wires, tree growth in line corridors, geographical environment, crossings and other conditions. These photos will be included in the project acceptance report and digital archives, and will be accumulated and improved to form a database of typical project defects, providing the most comprehensive and basic original data for the reliable operation of the power grid, and at the same time providing guarantee for the "zero-defect" operation of the project.
In the next step, the company will further explore the data value of the standardized acceptance typical defect database, use typical neural networks to achieve independent classification and identification of collected images, automatically identify and alarm power grid engineering defects and form reports, and promptly report them to construction, supervision and construction personnel. , operation and other participating parties push information to realize process management of defect identification, information reminders, defect rectification reporting, and rectification confirmation, and realize digital and intelligent transformation in the field of power grid infrastructure.
