The Analysis of Bilateral Power Supply for AC Electrified Railway


In China, the unilateral power supply has been used in AC electrified railway, which depends on the management mode of power system. For better economic and technical indexes, all-parallel AT traction system is widely used in passenger dedicated line. In this paper, the equivalent circuit model of unilateral power supply and bilateral power supply is investigated, and based on this model, the difference between unilateral power supply impedance and bilateral power supply impedance is discussed.
