| Abstract: | Steady-State Calculation of Short-circuit Current in DC Traction power supply system is important for the design of urban rail transit power supply system.This paper discussed the mathematical model of DC traction power supply system and the calculation method and the flow chart of steady-state short-circuit current,what’s more,it designed the calculation program and interface of steady-state short-circuit current,and gave the simulation results of the line 3 of Shanghai subway on short-circuit of DC tractive network,meanwhile the conclusion was compared with the measure data of subway lines to prove its veracity,and finally it gave the simulation results of the line 6 of Beijing subway on zero fault impedance of DC tractive network. |
