description: The final qualifying work includes six chapters, in which the main stages of designing a block transformer substation are considered in detail. The first chapter contains a brief description of the consumers and defines the main tasks. The second chapter is devoted to the choice of the optimal location of the substation, the choice of types of power transformers, the determination of their rated power and the verification of their operation in post-emergency modes. In the third chapter, the section of conductors is selected and they are checked for relative voltage losses, as well as checked for resistance to emergency mode currents. In the fourth chapter, the calculation of short-circuit currents on the higher and lower sides of the voltage in the maximum and minimum modes is made. In the fifth chapter, the choice of the main electrical equipment was made and a check was made according to the main criteria. The sixth chapter deals with the organization of safety, fire safety and lightning protection of the substation. At the end of the work, the main results of the design are summed up.
