description: The thesis project consists of an introduction, four main sections, a conclusion and a list of sources used. The first section is overview and staged. The content of the section includes the characteristics of the design object, as well as the choice of the main power supply scheme. The second section is calculated. To design a reliable power supply system, a set of calculations was carried out to determine the calculated load of group and individual consumers, according to the reliability category assigned to them, the cross-sections of cable lines and busbars were selected, a check was carried out for permissible relative voltage losses and the calculation of single-phase and three-phase short-circuit currents in the most distant point on the diagram, relative to the power source. The third section is devoted to protective measures. The section describes the main measures that have been taken to protect people from electric shock. The fourth section is devoted to operational safety and environmental protection. In the conclusion, the results of the work are summed up and the main conclusions are drawn.
