Case Study of a State Grid 220kV Substation Intelligent Inspection System Project
Power and Utility Tunnels

A 220kV substation of the State Grid Corporation of China covers an area of ​​9,900 square meters, with complex internal conditions and significant inspection challenges. Guozhi Robotics, utilizing a variety of inspection equipment including wheeled inspection robots, rail-mounted inspection robots, and fixed cameras, and comprehensively applying technologies such as digital twins, deep learning, and edge computing, has created an online intelligent inspection system for the substation. This system enables unified access to multiple devices, visual management, and expert-assisted decision-making, optimizing the substation's operation and maintenance model and achieving intelligent and coordinated operation of the entire system.
