Disturbing effects in rail vehicle traction drives

The paper dealt with the research focused on the problems of electromagnetic compatibility (EMC) - disturbing effects of traction drive with permanent magnet synchronous motors (PMSMs) which is used as a wheel drive for wheel multi-axle vehicle. The simulation mathematical models representing the vehicle with four PMSM drives are utilized in this research. The real drive (testing stand), which is placed in the laboratory at Jan Perner Transport Faculty (JPTF), was a base for simulation models. The simulations were done by Matlab Simulink. The effects of various strategies of control and various types of filters used at drive converters of four-wheel drive were considered from the viewpoint of the research of disturbing currents of this vehicle drive. The whole line of the harmonics and the significant subharmonic and interharmonic components occurred at previous stages of the researches on the level of experiments and also on the level of simulations of current harmonic spectrum at the configuration of one drive. The analyses of possible versions of bogie configuration were investigated for these reasons. The selected significant results of the mentioned research are specified in the conclusion of the paper.
