ZHONGSHEN, China, 22 August 2024 /PRNewswire/ — Recently, Xuzhou has been experiencing persistent high temperatures and the load on the entire grid has repeatedly reached record highs. Xuzhou State Power Company relied on the independent research and development of the “Navigator” series of drones to intelligently test transmission, conversion and distribution equipment, thus ensuring reliable power supply and a cool summer for residents in mid-summer and promoting economic development in low-altitude areas.
Build an industrial chain of electricity inspection drones to support low-altitude economic development
Recently, State Grid Xuzhou Power Supply Company held a conference on the “Leader” low-altitude UAV system technology brand. The “Leader” low-altitude UAV system technology brand was introduced to the public for the first time. The planning of the panoramic display spectrum has been completed, and the system is a highly autonomous intelligent UAV product.
“Navigator” is the first brand of flight operation technology in the system of State Grid Xuzhou Power Supply Company, independently developed by the industrial unit Xu Dian Group. Since the release of the first generation in 2019, the upgrade to the fifth generation has been completed. Accordingly, the company has built a whole industrial drone chain integrating research and development, production, service training and application solutions, and has successfully taken a new path for the development of electric drones, which greatly supports the local economic layout of low-altitude power generation.
With the help of the “Navigator” UAV, the State Grid Xuzhou Power Supply Company has set up a drone inspection team of more than 30 people and has so far completed the inspection of 40,000 power line poles and towers with a total length of more than 9,000 kilometers of distribution network lines. In total, more than 27 million yuan Drone inspection contracts were won and the service covered four cities in the province.
Autonomous transmission inspection makes the network more secure
To 5 Augustthe sun was hot, on the 35kV Silver Bridge 32E line of Pizhou, accompanied by a low hum, a four-rotor drone equipped with high-definition cameras rose into the air to conduct precise independent inspection work on the transmission lines, which is a microcosm of the daily inspection of the UAV inspection center of the Xuzhou Power Supply Company of the State Grid. The UAV patrol environment has strong adaptability, cannot achieve “scanning” of blind corners, and greatly reduces the safety risks such as heat stroke caused by high temperatures and stings by poisonous insects that may occur during manual patrols. Since the beginning of this year, the center’s pilots have completed the inspection of 18,348 base poles and towers in the Xuzhou area, and helped find and correct 18,047 defects.
On-site distribution network inspection makes power supply more reliable
The UAV inspection center of Xuzhou Power Supply Company of the State Grid has selected 8 UAV pilots with high control level to carry out grid operation and maintenance services, inspect fault-prone lines and key sections of the distribution network, and grasp the operation of line equipment in real time to ensure that the hidden fault management has “no blind spots, no dead areas, and no omissions”. So far, a total of 850.95 kilometers of 10kV lines have been inspected, and 4,976 defects have been discovered and assisted in timely processing.
Intelligent inspection of substations makes operation and maintenance more efficient
In the 220kV Yangtai substation, UAV, high-definition video and robot connection realize “heaven and earth” three-dimensional intelligent inspection, eliminating the visual blind spot of intelligent inspection. Recently, the UAV inspection center of Xuzhou Power Supply Company of the State Grid, with the help of the UAV full-business platform developed by the provincial company, has carried out the application of UAVs in the special patrol of power grid early warning equipment, one-key double confirmation CIS control and other scenarios, and formed a large-scale and practical Xuzhou transformer UAV solution.
Next, the State Grid Xuzhou Power Supply Company will continue to meet the requirements of operation and maintenance inspection, give full play to the excellent characteristics of UAVs with multi-dimensionality, short distance, high precision and wide perspective, greatly improve the operation and maintenance efficiency of power equipment, and ensure the reliable regional power supply. At the same time, it will strengthen cooperation with higher-level institutions in the upstream and downstream industrial chain, accelerate the development of new quality productivity of intelligent inspection, and promote the prosperity and development of the regional low-altitude economy in the power field.
