Study of Droop Characteristic in Advanced Co-Phase Traction Power Supply System

Abstract:

The disadvantages of two existing traction power supply modes are analyzed and advanced co-phase traction power supply system based on three-phase to single-phase converter is studied in the paper. Then, the chain model of network and the constant power model of locomotive are established. According to the above results, further analysis of the circulating-impedance and the feasibility study of droop control in this system are presented. The circulating-current analysis results of the advanced co-phase traction power supply system and the droop control of the system are given in the end of the paper.
