Fuel Hydrogen cells become nowadays a major candidate to replace the diesel in powering
the traction locomotives since they offer low emission of pollutant gases, high efficiency,
and flexible modular structure without the need for installation of electrification infrastructure for railway networks. However, they cannot respond appropriately to the fast
load transients due to their slow internal electrochemical and thermodynamic responses.
Therefore, they shall be integrated with fast dynamics Li-ion battery cells to form a hybrid
power source for traction systems. Accordingly, this paper presents a development of a
new smart integrated power source of fuel hydrogen and Li-ion battery cells to supply dual
three-phase machines for driving the trains in railway networks. The developed control
management system is regulating the two power sources according to the train operational
modes as well as the battery state of charge. In addition to that, dual three-phase machines
offer several superiorities over the conventional three-phase machines such as lower
harmonic distortion and power losses along with higher power density and fault tolerance.
A designated railway line is nominated through selection criteria in this paper for the
implementation of the new smart drive traction system in HIL platform using Typhoon HIL
real time simulator. Moreover, an optimization analysis has been carried out to reduce the
overall hydrogen consumption with the same journey time spent for a designated railway
line using particle swarm optimization approach. Finally, a case study is presented to
illustrate a proof of concept for designing the hydrogen refueling station for such railways which are supplied by the new integrated power source of fuel hydrogen and Li-ion battery
cells. The case study investigates the site selection, operational assessment, and equipment requirements.
