DC auto-transformer (DCAT) traction power supply system has been studied for the rail potential and stray current issues in urban rail transit. By transferring rail current to the specific lines with supply voltage doubling, DCAT system helps mitigate the voltage drop and power loss issues additionally. Both voltage drop and power loss analysis of DCAT system with dynamic characteristics are carried out based on its equivalent model. Moreover, the voltage drop and power loss comparisons between DCAT system and the existing system are analyzed in detail. Finally, extensive simulation results verify the theoretical analysis effectively.
