When designing and operating traction power supply systems (TPS), special attention is paid to the safety of the operation of transport power facilities. One of the determining factors of such impacts is the possibility of the appearance of induced stresses on extended metal structures located along the railway route. In modern conditions, characterized by the large-scale use of digitalization tools, the choice of such activities should be based on computer simulation. Therefore, it is necessary to develop algorithms for determining the induced voltages that are created by traction networks. For this, digital models can be used, which are based on the methods for determining the TPS modes implemented in the Fazonord software package. The article describes computer models that make it possible to determine the induced voltages on a pipeline equipped with insulating flanges, which are used for the purpose of electrochemical protection of a structure. The practical use of these models will make it possible to reasonably choose measures to reduce the negative effects of induced voltages on personnel servicing the structure.
