Abstract

This paper deals with the problems of mathematical modeling of electrical devices. In this work the computer model of the multi-winding traction transformer with values of its resistances, inductances and capacities is shown. The parameters of model have obtained by the approved techniques. The specified model is created in Matlab Simulink software environment. The adequacy of model is confirmed with transformer test results. On this basis simulation of transformer operation for currents of the increased frequency in the range of 50 Hz – 100 kHz is carried out. Results show absence of the dangerous resonant modes in this range. In the future time described model may be used for calculation of electromagnetic processes in all subcircuits of electric system “traction transformer – power converter – asynchronous drive” for modern electric rolling stock electromagnetic compatibility providing. It is necessary condition for it’s implementation on the Ukrainian railways.
