The article proposes a universal methodology for modeling DC traction power supply systems. The modeling method is based on dividing the system into AC and DC segments. The modeling results obtained using Fazonord AC-DC software confirm the advantages of using a twelve-pulse converter. Key findings show a 14% reduction in the maximum imbalance factor k2U and a 25% reduction in the total harmonic distortion (THD) factor. In addition, the minimum voltage at the locomotive current collector increased by 4%. This method is universal and can be used to determine the modes and quality indicators of electrical energy for various railway power supply systems and traction network configurations.
