In the AC/DC dual-system traction power supply system, the locomotive works in different power supply modes before and after phase breaking, which results in differences in traction return current characteristics and affects the combined rail potential distribution of different sections. A model for AC/DC dual-system traction power supply system is established by using CDEGS software, and the correctness and validity of the calculation model is verified. Given the mutual interference in traction return current between the AC and DC sections, the combined rail potential limit of the AC/DC dual-system traction power supply system is proposed, and the main factors affecting the combined rail potential distribution and its sensitivity are explored. Results show that when the rail insulation joints are not installed in the power free zone, the increase in the length of the power free zone can reduce the mutual interference in the traction return current between the AC and DC sections, leading to the reduction of the combined rail potential in the power free zone. The increase in soil resistivity can aggravate the mutual interference of traction return currents between the AC and DC sections, resulting in increase in the combined rail potential in the power free zone. The greater the rail-to-ground resistance of the DC section, the higher the combined rail potential for the DC section. The insulating joints in the power free zone between the AC and DC sections can change the reflow structure and avoid the out of limits of the combined rail potential. The first dual-system line in China is taken as an example, showing that the DC component of the combined rail potential can be reduced from 103.92 V to 60.20 V when the insulation joints are installed, which can ensure personal safety.
