Fast and Modular Implementation of Railway Lines Models for RT and HIL Testing of BEMU Trains

Development of battery-operated rolling stock is producing a renewed interest for the electrical model of DC catenaries. Battery Operated Trains are a feasible alternative to conventional Diesel-Powered Units, however the limited autonomy granted by batteries is typically incremented and optimized adopting partially electrified lines non-electrified sections are periodically with electrified sections in which dynamic recharge occurs. Often electrified sections correspond also high traffic sections in which conventional electric powered trains are also used while battery operated trains are performing their moving recharge. Resulting interactions between different kinds of rolling stock can negatively affect power efficiency of the line. On the other hand, a proper regulation of the battery recharge can also represent an opportunity to increase overall efficiency and electrical stability of the system. In this brief work some tools and methods are introduced to show their potential usage to explore some benchmark scenarios.
