Simulation of induced voltages created by the 25 kV traction network across the pipeline in ice melting mode

Abstract

Long metal structures and facilities can be located along the routes of electrified railways with 25 kV traction networks. A typical example of such facilities is pipelines designed to transport liquid or gaseous products. Due to the electromagnetic effects of electric traction networks, induced voltages can occur on structural parts, which are dangerous for the operating personnel. A set of special measures is needed to improve electrical safety and protect people from the influence of induced voltages. In the context of 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 simulation of railway power supply systems developed in Irkutsk State Transport University. The article presents the results of research aimed at the development of computer models designed to determine the electromagnetic effects of electric traction networks on the main ground-laid pipeline in the modes of ice melting.
