description: This work is devoted to the design of the electrical part of the traction substation, as well as to the study of the modes of operation of electrical equipment when the load changes, due to the increase in the number of trains on the railway section. Tasks that were solved during the study: 1. Study of the main regulations and calculation methods for solving the problems of preliminary design of electrical equipment of DC traction substations of railway sections; 2. Calculation and study of the loads of the Weimarn traction substation with an increase in the number of trains, according to the project schedule for 2025; 3. Selection of electrical equipment, study of its operating modes, development of switchgear circuits; 4. Calculation of the protection settings of the 3,3 kV switchgear and the feeder zones of the contact network. The work was carried out on the basis of the actual technical characteristics of the Mga â Lugskaya railway section and the project schedule of train movement for 2025. In the design and analysis, the methods of determining the electrical loads of the substation, based on the implementation of traction calculations, methods for calculating electrical circuits in normal and emergency modes, were used.
