On January 4, on the 330kV Lanji line of yaocaotai forest farm, Haidong City, Qinghai Province, the transmission operation and maintenance personnel of State Grid Qinghai maintenance company carried out three-dimensional modeling and independent inspection of the line according to three standards such as the technical guidelines for lidar scanning of UAVs for overhead transmission lines in high altitude areas. This series of standards is the first batch of enterprise standards in the field of UAV intelligent patrol inspection of overhead transmission lines in high altitude areas of Qinghai power system. It was prepared and issued by State Grid Qinghai maintenance company in 2021, which provides a technical basis for UAV intelligent patrol inspection of transmission lines in Qinghai Province.
In recent years, State Grid Qinghai maintenance company has gradually expanded the scale and coverage of UAV patrol inspection of transmission lines, deepened the intelligent patrol inspection system of Qinghai power grid, improved the quality and efficiency of operation, maintenance and repair, realized the interconnection between UAV and the panoramic intelligent operation inspection management and control system of Qinghai main power grid, used UAV aerial photography to collect data and built a real three-dimensional platform. In addition, it is gradually realizing the intelligent inspection operation of UAV and the visual management of transmission equipment, continuously improving the value ability of scientific and technological achievements to enable business innovation, and accelerating the scientific and intelligent transformation and development of power grid inspection.
Based on the gradually rich exploration and practical experience of UAV intelligent patrol inspection, the company has studied and prepared a series of industry forward-looking and guiding technical standards around the common problems, key technologies, service support and other important contents of UAV patrol inspection, so as to orderly guide the innovative application and integrated development of UAV intelligent patrol inspection technology in the field of power grid patrol inspection, In 2021, three enterprise standards in this field were issued, providing a standardized technical guidance framework for building an intelligent inspection system for transmission lines in high-altitude areas.
In this series of enterprise standards, the guidelines for lidar scanning technology of UAVs for overhead transmission lines in high altitude areas focus on the independent inspection technology of UAVs, provide a technical basis for the scanning operation using lidar technology in the three-dimensional line modeling and inspection route planning stage, and clarify the scanning range, equipment parameters, operation requirements, data acquisition, data processing, etc, It lays a technical foundation for the smooth development of UAV autonomous patrol inspection. The UAV patrol operation instruction for overhead transmission lines in high altitude areas unifies the UAV patrol operation standards in high altitude areas, provides all-round guidance for the standardized operation of UAVs in Qinghai power transmission specialty, and promotes the UAV patrol operation throughout the whole process of the construction of UAV intelligent patrol system. The technical guidelines for UAV operation and maintenance system configuration of overhead transmission lines in high altitude areas provides a theoretical basis for UAV system configuration, provides “logistics support” for the construction of UAV intelligent inspection system, and improves the overall level of UAV equipment in Qinghai electric power.
