description: To analyze this system, first of all, it was necessary to select such equipment as generators, step-up and step-down transformers, autotransformers, and the cross-section of wires of power lines. Then, the steady state operation was calculated by the software package "RastrWin". After that, measures were selected to achieve optimal levels of reactive power flows and voltages at the nodes. At the next stage, a single-phase short circuit was considered as an asymmetric short circuit. Then the short-circuit currents were calculated using the symmetrical components method and also with the help of the "EMTP" software. The Dymola software was used to consider the transient stability of a given system under various modes. During the study, the stability of the system to single-phase and three-phase short circuits was studied, and recommendations were made to improve its transient stability.
