Abstract: With the continuous expansion of the power system and the increasing number of substations, traditional manual substation inspections face more complex and cumbersome challenges. In order to improve inspection efficiency and on-site operation safety, the article designs and implements an intelligent remote inspection system for regional substations. This system divides the substation under the jurisdiction of a centralized control station into one or more areas. Each area is equipped with a remote intelligent inspection system. Coordinate factors such as network channel resources and required intelligent analysis and computing power. Utilize joint automatic inspection technologies such as robots, drones, surveillance cameras, and voiceprint monitoring devices to remotely inspect and detect faults in substations within the area. Significantly reduces the workload of manual inspections and operational safety risks. At the same time, it has improved the coverage, real-time performance, and accuracy of inspection. The practical application results of the regional remote intelligent inspection system in substations indicate that the system has good stability and scalability. It has brought significant benefits to the operation and maintenance management of substations.
