Power Quality Improvement in Traction Power Supply Networks
2013AC railway traction loads are usually huge single phase loads. As a result, a significant amount of Negative Sequence Current (NSC) is injected into utility grid. Moreover, harmonics and consumption of reactive power are further power quality problems that the supply network is encountering.

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.

Developments in d.c. traction power supply rectifiers
International Conference on Developments in Mass Transit Systems, 1998Rectifier theory and its application to diode-type power convertors to provide DC power supplies for urban electrified railway systems has long been established and used successfully throughout the world. Traditionally, limitations in diode power ratings lead to large numbers of diodes being required in the rectifier which resulted in the fused design ...
