Abstract
In order to study the interaction among the traction power supply, the train group and the operation dispatching of urban rail transit, a coupling simulation system of power supply system, trains and dispatching management is constructed. In order to solve the problems of different timescales and difficult cooperation operation for related subsystems, a multi-bus distributed real-time network architecture based on hierarchical management of communication data is established, and simulation management software is developed to facilitate the free expansion of the simulation system. Meanwhile, the track line, train operation and other large timescale subsystems are realized by the pure digital simulation. And the time-sensitive subsystems, such as train traction system, braking system, auxiliary power supply system and network system etc., are built by the semi-physical simulation. In this article, the system structure and the main implementation principle of each simulation subsystem are given in detail, and the system is tested and verified at the end. The results show that the simulation system can meet the expected requirements.
