Abstract: This paper describes the single-phase combined in-phase power supply scheme of unequal capacitance SCOTT transformer in rail transit AC 27.5 kV AC power supply system, and the feasibility of the scheme is verified by simulation. The application shows that the in-phase power supply device can effectively improve the train operation efficiency, the power quality and the energy efficiency of the traction system.

Keywords: rail transit; co-directional power supply device; 27.5 kV AC power supply system; operation efficiency; simulation verification
