Abstract

Governments all over the world are making considerable efforts to decarbonise railway transportation by switching out diesel propulsion systems for cleaner units as a result of environmental concerns. The electrification of railway lines is expanding quickly, but it is unlikely that all routes will be electrified because the large infrastructure expenditures cannot be justified by the number of passengers. As a result, it is anticipated that numerous lines will use a combination of electric and hydrogen traction, with the latter being supplied in part by fixed infrastructure and in part by batteries. Railway traction drives will then need to be modified to make room for these novel power sources. With regard to the new hybrid-electric systems, a thorough analysis of the traction motors and drives that are now on the market is included in this assessment. In particular, comparisons between conventional three-phase machines and permanent magnet synchronous motors with multiphase windings are made. In addition, the development of broad band-gap semiconductor devices has been considered while reviewing low- and medium-voltage multi-source power converters.

A double three-phase permanent magnet synchronous motor (DTPMSM) is used to analyse and compare with its three-phase counterparts. A comparison of traditional interleaved and proposed converter topologies are evaluated in terms of size and cost. The proposed traction converter and motor are simulated in a real-time simulator. The study aims to examine the speed and torque control of the DTPMSM as well as give a power-sharing analysis. The proposed traction module promises less volume/mass improvement and a decarbonised rail industry by better integration of renewable power resources, as illustrated in the preliminary findings. Therefore, the proposed power-sharing strategy with a traction module appears suitable for controlling the electrified rail applications as validated experimentally in this study through the Typhoon HIL real-time simulator platform.
