| Abstract |
An on-line simulator for DC-fed, VSl-IM rail traction drives has been created using a parallel computer. The simulator implements a D-Q axis transient model and produces time domain outputs of the system voltages & currents. torque and speed as the drive accelerates through a typical traction duty cycle. FFT spectra are available of all the time waveforms at user-defined windows. This paper describes the verification of the simulator. This is achieved by comparing simulated results of the harmonic spectra of the system variables with those obtained by measurements on a small-scala laboratory model. The simulated and experimental results reported in the paper occur near a modulation step change and are in agreement within the bounds of experimental error. |
