Description
Summary:The paper presents the real-time simulation of DC traction power supply systems for electric trains. It works as a virtualization solution for DC traction power supply systems, facilitating the testing of real-time control strategies and the improving energy efficiencies. The study explores the advantages of real-time simulation over traditional offline simulations, the challenges in developing accurate simulation models and control strategies, and existing studies on real-time simulators for railway systems. The paper also provides a background of TPSS modeling, focusing on the nodal grouping method and modeling trains within the system. OPAL-RT real time simulator was used to perform real-time simulations. Finally, the paper presents DC traction power supply simulation results and analysis and concludes with a summary of the key findings and future research directions.
