description: This work is devoted to the implementation of the connection to the power supply system of the traction substation "Apatity" of consumers of the horticultural association "Medik", the design of the connection scheme, the analysis and study of the established operating modes in the resulting electrical network with the calculation of the main parameters. In the course of this work, several tasks had to be solved. Based on them, overhead power lines were selected, a 0.4 kV overhead line was formed, and a complete transformer substation with a rated power transformer was designed. Next, the calculation of the steady-state operation of the upgraded network was carried out, taking into account the possibility of adjustments to ensure the required conditions for the quality of transmitted electricity. For a more reliable calculation of the system, the RastrWin3 software package was used with the construction of a graphical model with all the obtained mode parameters. The next task was the analysis of single-phase and three-phase short circuits with the calculation of current values in an analytical way. In the final part, the loads were calculated and the center of electrical loads was determined.
