Design and Research on Green Intelligent Power Supply System for Urban Rail Transit

Objective At present, the urban rail transit power supply system faces problems such as low monitoring information interaction and integration, unbalanced power management functions, insufficient systemization and low intelligence in power supply operation and maintenance. Therefore, it is necessary to study the design of a green and intelligent power supply system for urban rail transit and build an intelligent power supply system with holographic perception, information interaction, reconstruction self-healing, intelligent operation and maintenance, so as to achieve the requirements of a safe and reliable, intelligent and efficient, green and low-carbon, high-quality and sustainable urban rail transit development. Method Based on an analysis of the composition, characteristics and requirements of urban rail transit power supply system, the intelligent power supply system architecture of urban rail transit is proposed, which builds upon the intelligent power supply facilities and integrates the intelligent power dispatching system, power management system and intelligent power supply O＆M（operation and maintenance） management system three core business functions on intelligent power supply facility basis, and the functions and technical requirements of each section are explained. Result ＆ Conclusion The intelligent power supply system of urban rail transit can realize the goals of intelligent power dispatching, scientific equipment O＆M, standardized business process, and clear asset management, providing reference for the construction of new lines for urban rail transit power supply system, upgrading and transforming existing lines towards green intelligence.
