description: During the execution of this work, an analysis of steady-state and transient processes in the 110/35 kV system was performed. To do this, a calculation was carried out for the corresponding processes, consisting of 4 main parts. During the first stage, suitable equipment was selected, namely power and three-winding transformers, generators, and power transmission lines. In the second, using the Â«RastrWinÂ» software package, the system given in the task was modeled in steady-state mode. The voltages in the nodes satisfying the permissible values of Â± 5% of the nominal values of the system were found for the mode of maximum and minimum loads after installing the BSC in the necessary load nodes. After that, a manual calculation was carried out, as a result of which the obtained voltages converged with the calculation of the Â«RastrWinÂ» software package. During the third part, the manual calculation of currents and voltages of a two-phase short circuit was carried out using the method of symmetrical components. Vector diagrams for currents and voltages were also made. Subsequently, the corresponding short circuit was simulated in the Â«EMTPÂ» software package, the results of which coincided with the values obtained during manual calculation. In the last part, dynamic stability was calculated for the steady-state mode of the system, as well as for two-phase and three-phase short circuits. The system lost its dynamic stability during a three-phase short circuit, so measures were taken to improve it, namely the addition of a speed controller and changing its parameters.
