“…The acceleration that a train can produce is related to the traction force of the motor and the train resistance [17]. The acceleration of a train a i , is the value obtained by dividing the effective traction force of F e f f in kN by the dynamic mass of m dyn in tons, and it is expressed in Equation (1). The suffix i stands for calculation step for time, distance or velocity.…”

“…Recently, various next-generation electric vehicles and railroad systems are being introduced. Additionally, eco-friendly hydrogen railroad vehicles that cause low carbon, cause less fine dust pollution and energy cost reduction are being developed [1] in Korea. Meanwhile, in the traction power supply system (TPSS) sector, especially for DC metros, energy storage system (ESS) aided applications are one of notable research topics [2].…”

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.

Conventional diesel railway vehicles produce many air pollutants. In order to solve this problem, railway vehicles using eco-friendly hydrogen fuel cells are emerging. The main difference from the conventional traction motor is that it does not control the phase back electromotive force (phase-BEMF) separately at the maximum speed. Because of this, it should reduce the use of permanent magnets yet increase their size due to necessary high current. This paper performs the interior permanent magnet synchronous motor (IPMSM) design to meet the harsh electrical and mechanical constraints. Although the basic design is carried out to satisfy the design constraints, structural problems occur. These are resolved through the optimization process to attain the optimal design of a 314kW-class IPMSM for railway vehicles using hydrogen fuel cells.
