Application of ETAPTM eTraXTM software package for digital simulation of distribution network that feeds an AC traction power supply system [PDF]

E3S Web of Conferences, 2020
Voltage unbalance in power systems feeding AC traction power systems is a worldwide known problem. One of the main aspects of this problem is the negative effect of voltage unbalance on motor loads causing operating problems and economic damage.

Accounting power supply schemes for traction substations in the calculation of short circuits in the AC traction network

Вестник Научно-исследовательского института железнодорожного транспорта, 2019
When calculating short-circuit currents in the AC traction network, it is assumed that each of the traction substations receives power from uncoupled external power supply sources with known resistances. In some cases, especially when powering a group of

A Novel Co-Phase Power Supply System for Electrified Railway Based on V Type Connection Traction Transformer

Energies, 2021
Power quality and neutral section are two technical problems that hinder the development of electrified railway to high-speed and heavy railway. The co-phase power supply technology is one of the best ways to solve these two technical problems.
