Discussion on DC and AC Power Quality Assessment in Railway Traction Supply Systems [PDF]
2019 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2019 The assessment of the power quality could be a valuable tool to foster the efficiency of the whole railway system by “awarding” the good power quality delivered and absorbed. Power quality is a well-addressed topic in conventional AC 50/60 Hz power systems and many procedures, algorithms and measurement systems were presented in international standards

A Novel Co-phase Traction Power Supply System in Electrified Railway
Journal of Physics: Conference Series, 2023 Abstract The electrified railway has power quality problems such as three phases seriously unbalanced, large harmonics, and reactive power. In addition, the neutral section exists at each power supply section, which restricts the development of the high-speed and heavy-haul railway.
