MODELING OF ELECTROMAGNETIC EFFECTS OF TRACTION NETWORKS ON LONG METAL STRUCTURES
Long metal structures and structures can be located along the routes of electrified railways with 25 kV traction networks. Typical examples of such structures are pipelines for the transport of liquid or gaseous products. In some cases, these structures may be adjacent to agricultural areas. Due to the electromagnetic effects of traction networks, induced voltages can occur on structural parts, which are dangerous for service personnel, as well as for workers in the agro-industrial complex. To increase electrical safety and protect people from the effects of induced voltages, it is necessary to use a set of special measures. In the context of the digitalization of the electric power industry, the choice of such measures requires the use of computer technologies, which can be implemented on the basis of methods and tools for modeling power supply systems for railways developed at the Irkutsk State University of Railways (ISUR). The article presents the results of research aimed at the development of computer models designed to determine the electromagnetic effects of traction networks on the main pipeline of ground laying in the modes of melting ice.
