Abstract： With the continuous expansion of urban rail transit scale，the complexityof the network has increased significantly，imposing higherrequirementsonthereliabilityandstabilityofthepowersupplysystem.Asanimportant means to improve power supply reliability， inter-line supportive power supply has gradually attracted widespread attention.This paper conducts an in-depth studyon the related technologies of inter-line supportive power supply forurbanrail transit，analyzes itsworking principles，advantagesand implementationprinciples，and discusses its application effects in urban rail transit combined with the practical application case of Nanjing Metro Line 7. On this basis，this paper explores the construction of a network-level energy management system to realize the unified dispatching of main substations and 35kV medium-voltage supportive power supply， so as to meet the unified dispatching demand of the power supply system under the networked operation mode of urban rail transit.
