description: The topic of the presented final qualifying work includes not only the analysis of steady-state and transient modes in the 220/110 kV power supply system, but also the adoption of measures to increase dynamic stability. The work consisted in the following: it was necessary to select the main power equipment according to the initial data, also with the help of these data to "manually" calculate the steady-state operation of the system, it was also necessary to obtain the steady-state mode using the RastrWin software package. After that, the parameters of both currents and voltages of a two-phase short circuit to earth were calculated. In order to remove the necessary oscillograms of currents and voltages, as well as to verify the correctness of the calculation, a model was modeled in the EMTP software package. The last point of the work is the calculation of dynamic stability and measures to increase it. To do this, the parameters were initially set to relative units in order to use them in the Dymola program in the future. According to the results, a short-circuit experiment was carried out at the specified point and measures were also taken to increase the dynamic stability of the system.
