The overhaul and maintenance of the substation operation site is one of the important contents of the power system safety management. With the development of artificial intelligence and surveillance cameras, face recognition technology is widely used in power system maintenance work. In this paper, it is proposed to establish an integrated system of maintenance platform. By using the residual network (ResNet) model to build a high-precision face recognition system, it can provide remote maintenance certification for electric power personnel. The integrated system helps the substation personnel to reduce communication cost, realize equipment maintenance inspection, and complete the current status check of the equipment and the physical integrity check of the substation area. This face recognition-based remote substation maintenance working mechanism greatly improves the on-site safety of the power system operation, and also reduces unnecessary management expenses and management costs.
