The in-phase traction power supply system composed of a balance transformer and an integrated power flow controller can solve the problems of negative sequence current, harmonic current, reactive current compensation and phase separation. The compensation principle existing in the power supply system is analyzed, At the same time, the influence of traction power supply system with regenerative braking on the power quality of power system is compared. It is pointed out how to balance energy feedback to the power grid under braking condition and achieve the purpose of energy saving. This paper introduces the compensation principle and regenerative braking characteristics of in-phase traction power supply system.
