Research on Bilateral Power Supply Technology of Electrified Railway

摘要

This paper analyzes the advantages of bilateral power supply systems for electrified railway. Firstly, the equilibrium current is analyzed under different external power supply conditions. A method of reducing the equilibrium current is proposed, and the voltage loss of the traction substation caused by this method is solved. Next, the electrical performances of traction power supply system are analyzed, including current distribution, impedance and voltage loss. Finally, the model of bilateral power supply system was built, and the theoretical analysis was simulated and verified by Matlab/Simulink.
