description: In the first part of the work was selected equipment of the power system: transformers, autotransformers, overhead lines and generators. In the second part of the work, the steady-state mode of the system was calculated manually and with the help of the software "RastrWin". Also, the mode of maximum and minimum loads was simulated and their optimization was performed. In the third part, analytical short-circuit calculation and calculation in the program "EMTP" were carried out, two-phase short-circuit to earth was investigated. In the final part of the work with the help of the software "Dymola" the dynamic stability of the electric power system was investigated, the limiting time of disconnection of single-phase and three-phase short-circuit was found, measures to improve the dynamic stability of the system were carried out, three-phase automatic reclosing of the line and impulse unloading of the generator turbine were applied, which allowed to increase the limiting time of disconnection of the short-circuit. As a result of realization of the final qualification work the skills of equipment selection, calculation of steady-state mode analytically and with the help of a program complex, and also skills of calculation of short-circuit currents were received and practiced.
