A comprehensive computer simulation model of a railway locomotive

A complete electrical system computer simulation of the Queensland Rail class 3100/3200 locomotive has been completed. The Simulink simulation software package which has been utilised offers an easy to use graphical user interface which readily allows the manipulation of system variables during the run time. The simulation model has been calibrated and validated against measured results made on a locomotive in normal revenue gaining service. A simulation model is a valuable tool for the investigation of fault conditions. In this paper the models value is illustrated by its application in gaining a better understanding of the effects of harmonic currents on transformer and power factor correction system performance.
