Performance Evaluations of DCAT Position for the Floating DCAT System in DC Railways

DC auto-transformer (DCAT) traction power supply system has been studied for the stray current and rail potential issues in DC railways, and the solidly grounded DCAT system of equal sections has been analyzed in detail. However, in practice, the floating scheme more tends to be adopted in DC railways, and the sections of DCAT system is hard to achieve complete equality. Therefore, the performance evaluations of DCAT position for the floating DCAT system were proposed in this paper. The performances of floating DCAT system with equal sections were analyzed comparing with the existing system. Then the theoretical analysis and the relationships between DCAT position, rail potential, and stray current were discussed in detail. Finally, the correctness of the proposed analysis was verified by the simulation results.
