Simultaneous DC Railway Power System Analysis Method Using Model-Based TPS

Abstract

This paper focuses on the development of a model-based train performance simulation with the practical train operation data using MATLAB Simulink. The developed program uses input operation data of a DC 1500 V metro line. And the simultaneous and multi-rate simulation for DC metro was performed to interface train schedule data with actual railway electrification system and vehicle. In the simulation, the voltage and power measured at each substation are provided during the traction, coasting and breaking mode. From this study, railroad vehicle load can be virtually modeled in the system internally and contribute to verifying new parts of the overall railway electrification systems.

“…Regenerative Energy Storage Systems are installed at the stations and linked to the traction power circuits. As a train centers a station and slows down using regenerative braking, the energy fed back to the traction power supply system is stored in the batteries [40][41][42][43][44][45][46][47][48][49][50].…”

“…According to [46][47][48], for HCMC, the demand coefficient for calculating traffic capacity is 1.0, and load parameters as Table III. The simulation calculation method using MATLAB R2017b/Script and results for the operating plan are summarized in Table IV.…”
