Description
Summary:A mathematical model of the “traction network–ac electric locomotive with four-quadrant converter” electrical system is proposed. Analysis of electromagnetic processes is carried out. Calculation formulas of the system parameters are derived, and the results are presented in graphs. A mathematical model of the electrical system is proposed. Software implementation of the proposed mathematical model and numerical studies of reproducible electromagnetic processes are carried out in the Simulink package of the MATLAB computing environment. Conclusions about the electromagnetic compatibility of electric locomotives with different traction converter structures are drawn.
