| Abstract |
A railway traction system simulator intended for the study of electrical interference produced by converter-fed traction drives is described. The simulation model comprises a neutral-pont-clamped inverter drive, a 3 kV DC 12-pulse rectifier substation and a section of traction line. Time and frequency domain simulation results demonstrate the influence of the system DC current and non linear traction line impedance on the production of higher frequency harmonics in the catenary power supply circuit. |
