DESIGN, SIMULATION AND CONTROL OF HYBRID AND BATTERY ELECTRIC TRAINS

Battery-Electric and Fuel Cell Hybrid Rolling Stock are a feasible and sustainable alternative to ICE (Internal Combustion Engines) propulsion systems that are currently adopted to provide railway service on not electrified lines. About half of the lines in Western Europe are still not electrified, while in the rest of the world, a large part of the existing lines are still operated by Diesel-Electric and Diesel-Hydraulic-propelled trains. So, this solution can really contribute to further improving the sustainability and environmental impact of railway lines. In this work, authors propose a parametric simulation model that is used to evaluate the potential use of this technology considering different kinds of composition and foreseen services also investigating the more promising scenario of “Partially Electrified Lines” in which short, electrified sections are used to recharge vehicle storages periodically. In this work, the whole study is generalized with respect to an innovative and general layout of the power management system that can be easily scaled and customized to evaluate different solutions and scenarios.
