| Abstract: | Obtaining the transient process of the short-circuit currents in DC traction power supply systems is significant for setting calculation of the feeder protections. Combined with the measured data from Beijing Metro lines, this paper not only gave the electrical parameters of the DC traction power supply circuit which is consisted of the contact rails and the running rails, but also established the mathematical model of the whole system included 24-pulse rectifiers, meanwhile the power system simulation modu... |
