description: The theme of the final work: "Design of a block complete transformer substation 10 / 0.4 kV in the Kalininsky district of St. Petersburg." The volume of the thesis is: 80 pages of text, 26 figures, 10 tables, 32 formulas, 23 sources of literature. Key words: power supply, oil transformer, substation, power losses, voltage losses, switchgear, short circuit, grounding device. The purpose of this diploma project is to design a reliable and modern transformer substation in modular design, operating at a voltage class of 10 / 0.4 kV. To achieve this goal, the following series of electrical calculations was performed: â¢ determination of the required transformer capacity for power supply of power consumers of 1 and 2 categories of reliability; â¢ selection of the brand of power step-down transformers; â¢ selection of outgoing cable lines, followed by checking for permissible relative voltage losses; â¢ calculation of power losses in cable lines and power transformers; â¢ calculation of short-circuit currents on the high and low sides of the voltage; â¢ calculation of the resistance of the grounding device; â¢ selection of electrical equipment and protection devices. In addition to electrical calculations, the diploma project analyzed the current state of power grids in St. Petersburg and the process of phased construction of block transformer substations.
