description: The subject of the graduate qualification work is "Selection of the equipment and electrical modes calculation in the 500/220 kV power supply system". The given work is devoted to the study of the 500/220 kV PSS and the optimization of its operation in steady-state and emergency modes. The research includes the following tasks: 1. Selection of the main equipment: generators, transformers, conducting parts. 2. Calculation of the PSS steady-state mode "manually" and using the software package "RastrWin". 3. Calculation of currents and voltages of an asymmetric short circuit "manually" and using the software package "EMTP". 4. PSS static and dynamic stability studying in the software package "Dymola" and the choice of actions to improve the dynamic stability of the system. The main calculations were performed by obtaining equivalent circuits and considering some assumptions. To calculate the asymmetric short-circuit, the symmetrical component method was used. Based on the calculation of the steady-state mode, actions required to maintain the normal voltage levels in the nodes and the active and reactive power flows in the PSS have been determined. As a result of the dynamic stability study, critical short circuit clearance time for different cases has been determined and actions to improve dynamic stability have been selected. The implementation of the single-pole reclosing and automatic voltage regulator with power system stabilizer have been chosen as such actions.
