description: The presented work involves modeling and subsequent exploration of the 110/330 kV power system section. Certain amount of operations were performed while solving this problem: 1. Selection of basic power system equipment: transformers (two-winding and three-winding), generators and choice sections of power transmission lines. 2. Calculation of the steady-state mode by estimating the voltage level in each of the nodes and power flows in each of the branches of the system, and also by using RastrWin software. 3. While simulating a two-phase short circuit between AT1 and AL2, parameters of the system were calculated by the method of symmetric components. 4. By using EMTP special computing complex program, the needed waveforms at the point of a two-phase short circuit were derived. Further, a comparative analysis of the "manual" and software calculations was made. 5. Using the Dymola computing program, the dynamic stability of the two-machine power system was reviewed in detail. Determination of the cut-off time limit for two-phase and three-phase short circuits. Conducting an experiment to increase the duration of a three-phase short circuit, by enabling sequential electric braking.
