Abstract
According to the unbalanced load of traction power supply circuit of electrified railway, this paper takes the impedance matching balance traction transformer of high-speed passenger rail lines as the research object. Based on the voltage balance equation, winding connection principle and symmetrical component method of transformer, the load current unbalance characteristic of the balanced traction transformer is studied; according to the specific working conditions of high-speed passenger rail lines, the variation characteristics of the load characteristics of the balanced traction transformer are analyzed, providing a reference for the operation and control of high-speed passenger rail lines
