Power Quality Assessment in Railway Traction Supply Systems [PDF]
IEEE Transactions on Instrumentation and Measurement, 2020 The assessment of the power quality (PQ) could be a valuable tool to foster the efficiency of the railway systems. PQ is a well-addressed topic in conventional ac 50/60 Hz power systems, and many procedures, algorithms and measurement systems were presented in the international standards and widely discussed in the scientific literature.

A hybrid railway power conditioner for traction power supply system
2013 Twenty-Eighth Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2013Co-phase traction power supply system was proposed for supplying the long-distance electrified railway without neutral sections. However, a railway power compensator (RPC) needs to be installed in each substation together with the traction transformer for improving the power quality.

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.
