Traction Power

The article presents a mathematical model of electric traction vehicle movement in a given power supply area. Starting from the presentation of the basic features of the 3 kV DC traction power supply system used in Poland, the author presents a simulation model of electric traction vehicles movement, which allows to determine the mobility and current - voltage possibilities on a selected railway line. The obtained simulation results fully confirm the possibility of using the model as an aid in the design, modernization or diagnostics of existing railway lines and train traffic.

Traction Power

Steel pipelines for transporting oil and gas can run along the routes of AC main railways. As a result of the electromagnetic influence of traction networks on pipes having insulating coatings, voltages can be induced that are hazardous to personnel who operate the pipeline. The report addressed the issues of modeling the electromagnetic effects of a promising traction network of 94 kV on a steel pipeline with a diameter of 250 mm laid on the surface of the earth. Computer simulation showed that at a distance of 100 meters from the railway line to the pipeline, the maximum induced voltage reaches 100 V, which is more than one and a half times the permissible value. This factor must be taken into account when designing prospective traction power supply systems in the areas of their convergence with main pipelines
