Study of the influence of AC railway traction network on adjacent devices using simulation modeling

The article investigates the possibility of joint operation of the traction network of alternating current railways and related devices subject to electromagnetic influence using simulation modeling in the SimInTech and Elcut programs. The distributed nature of the line parameters and non-sinusoidality of the supply voltages are taken into account during the modeling. The voltage and current values obtained in the SimInTech program are the initial data for modeling the electromagnetic field pattern in the Elcut program. The results of modeling electric and magnetic fields are presented, which allow to estimate the intensity of the fields, their tension, the value of the induced voltage in the affected object. The prospects of scientific research in the field of analysis of electromagnetic fields created by the traction network of alternating current in various modes of its operation are shown.
