Exploration and Practice of Intelligent Operation and Maintenance of Long-distance Ultra-high Voltage Underground Cables Supported by Digital Twin Technology

In modern society, electricity resources are strategic resources in national strategies. In order to maintain the stable input and operation of electricity, it is necessary to carry out the operation and maintenance of high-voltage power cables, and handle and manage various unexpected work. Therefore, it is necessary to use high-tech means to effectively manage high-voltage cables, in order to promote the healthy development and development of China’s society and economy. This article explored the intelligent exploration and practice of long-distance ultra-high voltage underground cable power operation and maintenance supported by digital twin (DT) technology. Firstly, it introduced the relevant knowledge of cable power operation and maintenance and DT technology. Finally, the progressiveness of the long-distance ultra-high voltage underground cable power operation and maintenance supported by the DT technology was verified through experiments (the cost of the cable power operation and maintenance system designed based on this paper was saved by 60%, while the cost of the traditional system was saved by 30%).
