Wave processes in alternating current traction network depending on parameters of power supply system

Abstract

The article considers a mathematical model of the AC traction power supply system taking into account stationary and nonstationary wave processes. The model allows you to analyze the effect of system parameters on electromagnetic processes
at its various points. The time diagrams of currents and voltages on the feeder traction substation at different modes of operation of the electric rolling stock and its distance from the traction substation, obtained using the above mathematical
model. When modernizing and creating new power supply facilities, it is possible to use the proposed mathematical model
for calculating electrical parameters of traction substation equipment and contact network, coordinating the operation
of traction and external power supply systems, evaluating electrical energy quality indicators and electromagnetic compatibility.
