Abstract

In DC railways, the running rails are used as the return path for traction current, which inevitably leads to stray current and rail potential issues with poor insulation. However, the effects of existing solutions are limited, so DC auto-transformer (DCAT) traction power supply system (TPSS) is analyzed in this paper to solve the problems of stray current and rail potential fundamentally. Compared with the existing TPSS (E-TPSS), the mathematical analysis and simulation results show that DCAT-TPSS may solve both stray current and rail potential issues, which further reduce the voltage drop and power loss of power supply lines additionally.
