Modeling and Simulation of Multi-Vehicle DC Traction Power Supply System Based on MATLAB/Simulink

DC traction power supply system is an important part of urban rail transit. The modeling of it is not only the basis of safe operation of urban rail transit, but also provides theoretical basis for failure mechanism analysis. In order to solve the problems caused by high traffic density and long power supply distance of suburban lines in the rush hours of urban rail transit, this paper established the integrated model of rectifier units-traction network-vehicle simulation on MATLAB/Simulink platform. Taking bilateral power supply mode as an example, the starting current of multi-vehicle in different locations and times in DC traction power supply system is analyzed. By comparing the simulation results, the characteristics are distinguished between multi-vehicle starting current and remote short-circuit current effectively to protect the DC traction power supply system reliably.
