Conference paper
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 482)

Abstract

Traction power system simulation is needed, not only before system construction or reformation, but also the sensitivity analysis for the parameters of existing line. Due to the special landscapes for tunnel section, parameter calculation method of wires in traction power supply system should be different from the other kinds of section. Take Wushaoling super long tunnel section as example, the simulation model of direct power supply system with return wire was built based on the multiconductor transmission line (MTL) theory. The characteristic impedance was used to dispose the end effect of the return current network, the impedance parameters of traction network were calculated through Tylavsky formulas. At last, Field tests were performed to validate the correctness of the simulation model, this modeling method could be promoted to the simulation of other tunnel sections.
