Journal ArticleDOI
High-Order Harmonic Resonances in Traction Power Supplies: A Review Based on Railway Operational Data, Measurements, and Experience
Kejian Song,Wu Mingli,Shaobing Yang,Qiujiang Liu,Vassilios G. Agelidis,Georgios Konstantinou +5 more
TL;DR: A comprehensive review of harmonic resonances in traction power supply systems based on operation data acquired from Chinese railways and multiple ground-based and on-board solutions for resonance elimination are presented.
Journal ArticleDOI
Windowed SHE-PWM of Interleaved Four-Quadrant Converters for Resonance Suppression in Traction Power Supply Systems
Kejian Song,Georgios Konstantinou,Wu Mingli,Pablo Acuna,Ricardo P. Aguilera,Vassilios G. Agelidis +5 more
TL;DR: In this article, a windowed selective harmonic elimination pulsewidth modulation (SHE-PWM) method is proposed to suppress the resonances in traction power supply systems (TPSSs).
Journal ArticleDOI
Interleaved Operation of Three-Level Neutral Point Clamped Converter Legs and Reduction of Circulating Currents Under SHE-PWM
Georgios Konstantinou,Josep Pou,Gabriel J. Capella,Kejian Song,Salvador Ceballos,Vassilios G. Agelidis +5 more
TL;DR: This paper demonstrates the interleaved operation of three-level converters under selective harmonic elimination pulsewidth modulation (SHE-PWM), and a controller for the circulating current within the legs of each phase is also proposed.
Journal ArticleDOI
A Three-Phase to Single-Phase AC-DC-AC Topology Based on Multi-Converter in AC Electric Railway Application
TL;DR: The simulation results indicate that this AC-DC-AC topology can not only satisfy the voltage and power requirements of traction load and solve the power quality problems, but also have its own superiorities in the application of electrified railways.
Journal ArticleDOI
Stochastic Process and Simulation of Traction Load for High Speed Railways
TL;DR: A probabilistic model to describe the pattern of traction load changing with time is built and it is pointed out that the size and frequency of load fluctuation, respectively, rely on the slope and length of the rail ramp.
