Based on the understanding of the characteristics and application advantages of physical ID technology, technicians have proposed an intelligent inspection technology for power systems using physical IDs as carriers to improve the efficiency of power system operation and maintenance inspections. In this regard, this paper first briefly explains the concept of physical ID, and then analyzes the construction method of the application foundation (support system) of intelligent inspection technology for power systems based on physical ID from two aspects: system architecture and technical route. On this basis, the application scenarios of this technology were discussed and summarized, aiming to help power enterprises understand the application advantages and implementation methods of intelligent inspection technology for power systems based on physical IDs, promote the improvement of operation and maintenance capabilities of power enterprises, and promote the development of smart grids towards mobility, convenience, and intelligence.
