This paper considers the problem of increasing capacity on the Lena-Vostochnaya-Novy Uoyan section of the Baikal-Amur mainline, which is one of the most important transport corridors in Russia. The possibility of increasing the volume of heavy trains is analyzed. To improve the efficiency of electrical equipment, reduce power losses and increase the capacity of railway transport, it is necessary to improve the traction power supply system. To achieve this goal, various technical solutions are used to increase throughput and carrying capacity.
The article analyzes the current state of the power supply system, simulates the railway section and performs a traction calculation. The problem areas on this section have been identified and the causes of problems in the movement of trains in these places have been investigated. A train timetable has also been created. Some ways of strengthening the site are considered and their characteristics are obtained. Comparisons of the listed reinforcement methods have been made with each other and before their implementation. Graphs of voltage changes in problem areas are constructed to analyze the resulting voltage value using various technical solutions.
Based on the data and parameters obtained, it is concluded that it is necessary to strengthen this site and choose the most effective solution to the problem in this area.
