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.

Interaction of Traction Substations in Phase Shift Technique Based Traction Power Supply Network
2021 4th Asia Conference on Energy and Electrical Engineering (ACEEE), 2021Voltage unbalance in public utility caused by the single-phase AC traction network is a significant issue. Simple formula-based estimation and load flow-based calculation of unbalance are commonly used but they do not take into account the interaction between traction substations in phase shift technique-based traction power supply network.
