Harmonic Analysis of High-Speed Railway System for Different Configurations of the Traction Power Line

This paper proposes a frequency analysis of the High-Speed Railway System. The analysis focuses on the currents flowing into the system's conductors when a harmonic source is applied. Different power line configurations are observed with the aim of verifying the potential presence of resonance frequencies in the range Hz. These last indeed could be interference signals for system internal equipment and other external proximity victim circuits.
