Modeling and Simulation of AC Railway Electric Supply Lines Including Ground Return
2018
IEEE Transactions on Transportation Electrification
Today's AC railway feeding systems are composed by several conductors with various connections to each other. The return current is shared between rails, ground wires connected to rails, ground; current flows to ground are determined by rail-to-ground distributed conductance. This paper gives formulas to deal with all these complexities, both for power quality and power frequency studies, integrating and combining previous studies which cover only part of them. Especially new in this paper is a
