Abstract

With the construction of new power systems, the intelligent transformation of substations has accelerated. Multiple services, including dispatching, centralized control, five-prevention systems, online monitoring, and UAV inspection, are becoming increasingly interconnected, while cybersecurity hazards are becoming more hidden and variable. Hami is a ten-million-kilowatt-scale desert, Gobi, and barren-land energy base as well as a bridgehead for Xinjiang power transmission. Large-scale wind and photovoltaic power stations are concentrated in this region, and “two DC and two AC” ultra-high-voltage transmission channels support cross-regional power delivery. Industrial control, new-energy regulation, and ultra-high-voltage coordination services are deeply intertwined, making network risks capable of cross-provincial transmission and directly threatening national power supply security and energy security. At present, substation cybersecurity hazard management lacks unified standards, detailed control rules for intelligent services are insufficient, and the precision of hierarchical control remains inadequate. Based on power safety standards and the operation and maintenance difficulties of Hami’s sending-end power grid, this paper reviews the shortcomings in current governance practices and constructs a standardized whole-life-cycle process covering hazard identification, grading, reporting, rectification, acceptance, and review, supported by corresponding guarantee systems and differentiated implementation strategies.
