The traction network design of the new three‐phase 3‐kV traction power supply system based on the limits of receiving‐end voltages and negative sequence voltage unbalance factor

IET Generation, Transmission &Distribution, Volume 17, Issue 9, Page 2070-2087, May 2023., 2023
Frequency‐ and current‐dependent closed‐form formula based on 4‐parameters equivalent tubular conductor (ETC) model is proposed. Based on the limits of receiving‐end voltages and voltage unbalance factor, a new equilateral triangle structure of the traction network (TN) is proposed which can completely solve the voltage unbalance issue at the receiving‐
