description: Theme of work: analysis of steady-state and transient modes in the 500/220 kV EPS. The study of the EPS was carried out in sections: Selection of EPS equipment and overhead line wire cross-sections, Calculation of the steady-state mode of the EPS manually, using the RastrWin3 software, Calculation of the single-phase short circuit currents manually using the method of symmetric components and in EMTP software, Calculation, improvement of the dynamic stability of the EPS. The selection of equipment was carried out according to the rated voltage, loading in normal and emergency modes. The choice of the cross-section of the overhead power line was carried out according to the economic current density, then cross-section was checked according to the permissible long-term current, corona discharge, and mechanical strength. According to the steady-state modes calculations, it is necessary to connect reactive power sources and regulate on-load tap changing of transformers to obtain the optimal steady-state mode. In this work, the K^((1)) was considered. As a result, currents, and voltages at site of K^((1)) were obtained manually using the method of symmetric components and using EMTP software. When calculating the dynamic stability of the EPS, specialized Dymola software was used. Based on the results of calculations of the dynamic stability of the EPS, it was decided to increase it by using sequential electric braking of the generators of the second station.
