The simulation of electromagnetic interaction of the components of transport electrotexnical complex

Background: The transport electrical complex includes many interconnected infrastructure components that ensure the safety of the operation of the entire system. The issues of protection against electromagnetic influences are becoming more relevant with the growth of traffic intensity. Aim: Evaluation of the degree of electromagnetic impact of traction networks on the cable line. Materials and Methods: Mathematical modeling is carried out using the finite element method and the COMSOL Multiphysics software package. Results: Current distributions in two typical traction power networks are obtained, taking into account the presence of a cable line in the zone of influence. The generated electric and magnetic fields and the parameters of the current induced on the sheath of the cable line are determined. Conclusion: The use of mathematical modeling makes it possible to decompose the influences into constituent factors and reveal the internal structure of the mechanism of interaction between the components of the transport electrical complex. The simulation results allow us to confidently fix the induced currents from the force electromagnetic fields on the cable sheath. These studies can be used in the development of modern means of protection.
