Hardware-In-the-Loop Simulation of Traction Power Supply for Power Flows Analysis of Multitrain Subway Lines

Multitrain systems are difficult to study due to the size of the system and its specificities. To tackle these difficulties, this paper develops a reduced-scale power Hardware-In-the-Loop (HIL) simulation dedicated to subway line emulations. Energetic macroscopic representation (EMR) is used to organize the HIL simulation. A first mono-train HIL simulation is developed and validated by experimental results. The HIL simulation is then extended to a two-train study to analyze the different power flows between subsystems.
