description: At the first stage of the work, the 500/220 kV power supply network was considered and investigated. The selection of electrical equipment was made: transformers, autotransformers, wire sections of power transmission lines. Based on the selected equipment, an analytical calculation of the steady-state mode of the system was performed, as well as the calculation of the steady-state mode in the RastrWin software package. The mode of maximum and minimum loads, taking into account compensating devices, is also considered. Further, relative to a certain point of an asymmetric short circuit, a replacement circuit of the electric power system was drawn up. Furthermore, the currents and voltages for a single-phase short-circuit to earth are calculated using the method of symmetric components. Vector diagrams of currents and voltages are constructed based on the obtained calculation results. As a verification of the correctness of the calculation, a similar calculation was implemented in the ATP/EMTP software package with the corresponding dependency graphs. In the next phase of the work, we examined our power supply network in terms of electromechanical transients. We were faced with the task of studying the EES for dynamic stability, i.e., studying the motion of the system after a finite perturbation. A single-phase short circuit was assumed as a disturbance. This study was implemented in the Dymola software package. At the final stage, we took measures to improve the dynamic stability of the system. As a system optimization, a single-phase automatic re-activation cycle was implemented.
