Braking energy inverter has been widely used in urban rail transit traction power system due to obvious energy-saving effect. Its DC side virtual resistance, also known as DC resistance, can have a significant impact on the DC side energy flow of traction power supply system (TPSS). This paper introduces the definition and implementation method of the virtual resistance and analyzes its effect on the TPSS. The simulation model of traction power supply system is established, and the rectified energy and inverted energy under different virtual resistance values are compared by simulation. The simulation results show that the virtual resistance can change the path of regenerative braking energy flow and the overall energy consumption of the TPSS.
