Study of resonances in 1 x 25 kV AC traction systems [PDF]
, 2015 AC traction systems are 1 x 25 or 2 x 25 kV 50-Hz single-phase, non-linear, time-varying loads that can cause power quality problems. One of the main concerns about these systems is voltage distortion, because adjustable-speed drives for trains may ...

Transient wave propagation analysis of a pantograph- catenary system
Journal of Physics: Conference Series, 2016 This paper proposes a systematic method to analyze the dynamic response of an overhead catenary with pantographs moving at constant speed. The overhead catenary is modeled as a onedimensional infinite-length string, which is periodically supported by hangers.
