| Abstract |
In the paper a simulation model of 3kV traction locomotive with AC drive controlled by Direct Self Control (DSC) method is presented. The locomotive is modelled using Saber software. The aim of simulation is to show harmonics occurring in power system of the locomotive (torque, phase current and
voltage, inverter input current, chopper input current) and in the end harmonics generated by the whole drive. Possible pulsations of line current may exceed requirements of compatibility with the supply and signalling system. Some spectra obtained from stiff voltage fed inverter are also shown. |
