description: The theme of the final qualification work: "Comprehensive reconstruction of the 400 kV Vyborgskaya substation". The work is devoted to the reconstruction of the electrical part of the 400 kV Vyborgskaya substation with a subsequent change in the substation's circuit diagram.Tasks that were solved during the design: 1) analysis of the role of the 400 kV Vyborgskaya substation in the Russian and Finnish energy systems and analysis of the design features of the substation; 2) justification of the necessity and scope of the reconstruction of the substation; 3) analysis of the influence of DC link on short-circuit currents; construction of equivalent circuits and calculation of short circuit currents; 4) choice of electrical equipment; 5) choice of substation circuit diagram. The work was carried out directly at the 400 kV Vyborgskaya substation, where a significant part of the materials was collected. In the course of the work, the threephase short-circuit currents were calculated, according to which the choice of electrical equipment with a voltage of 400, 330, 110, 20 and 10 kV was made. As a result, a project for the comprehensive reconstruction of the 400 kV Vyborgskaya substation was prepared, including the replacement of morally and technically obsolete equipment, as well as a change in the substation's switchgear diagram.
