description: This work is devoted to the development of a reconstruction option of substation No. 165 Petrogradskaya to increase the reliability of power supply to consumers of this substation. The main tasks solved in the course of work: 1. Search and analysis of general information about the substation, substation equipment and consumers powered by substation-165. 2. The choice of the rated load power of power transformers and the choice of power transformers. 3. Calculation of three-phase short circuit currents on substation buses. 4. Selection and testing of switching equipment on the sides of high, medium and low voltage. The work was carried out on the basis of actual data provided by the distribution network company of St. Petersburg and the Leningrad Region of PJSC Lenenergo and on the basis of theoretical data borrowed from the study guide L. Kuleeva, S.V. Mitrofanov, L.A. Semenova "Design of the substation", as well as on the basis of reference materials B.N. Neklepaev, I.P. Kryuchkov "The electrical part of power plants and substations." As a result, the reliability of the uninterrupted operation of the substation-165 was analyzed and technological recommendations were developed to increase the reliability of the uninterrupted operation of the substation. Based on the calculations, it was decided to replace two power transformers with a capacity of 2x63 MVA with two power transformers with a capacity of 2x80 MVA and replace all high-voltage switches at substation-165.
