The structure of urban rail traction (URT) power supply system is complex and includes multiple levels. Conventional modeling methods focus on a single level, neglecting the correlation between multiple levels, which cannot meet the requirements of accurate, efficient, and comprehensive analysis of the entire system. To solve this problem, this article analyzes the principle of multi-level interaction in the urban rail traction power supply system, formulates interaction strategies, and builds a URT simulation model based on multi-level modeling methods. Finally, simulations were conducted using examples to obtain simulation results that combine the macro scale of the system level with the micro scale of the station level. The results show this multi-level model has high accuracy and fast simulation speed. It can provide effective reference for the comprehensive design and operation of urban rail traction power supply systems.
