Increasing the Energy Efficiency of DC Traction Power Supply Systems
Russian Electrical Engineering, 2020In this paper, we consider means to develop and improve a dc traction power supply systems and its adaptation for high-speed mine lines. One way to improve and increase the efficiency of the traction power supply system is to increase the rated voltage in the dc traction grid up to 24 kV.

Power Analysis on DCAT Traction Power Supply System for DC Railways
2018 IEEE International Power Electronics and Application Conference and Exposition (PEAC), 2018For DC railways, DC auto-transformer (DCAT) traction power supply system may solve the rail potential and stray current and issues fundamentally. However, the load power may reach to millions of watts, and the starting current of trains may reach to thousands of amperes, which may lead to the high cost and volume of DCAT system.

DC side short circuit transient simulation of DC traction power supply system
2004 International Conference on Power System Technology, 2004. PowerCon 2004., 2005In urban railway transit, DC traction power supply system is adopted. Accurate analysis of DC side short circuit transient is important for design of new DC traction electrification system and assessment of the suitability of protection arrangement and power equipment. The model of the transformer/rectifier was analyzed.
