description: This work is devoted to the modeling and research of a section of the 35/110 kV power system. It covered the following tasks in detail: 1. Selection of the main equipment of the power system (generators, two-winding and three-winding transformers, cross-sections of power lines). 2. Calculation of the steady-state power transmission mode according to analytical formulas (obtaining voltages at all nodes and power flows along all branches of the power system). Calculation of the steady-state in the RastrWin software. 3. Calculation of voltages and currents at a single-phase short-circuit on the clamps of the generator G2 by the method of symmetrical components. 4. Simulation of a single-phase short circuit in the EMTP software, obtaining oscillograms of currents and voltages at the point of short circuit, and comparing the results of analytical and software calculations. 5. Analysis of the dynamic stability of a three-machine power system in the Dymola software. Obtaining the limiting time for tripping a single-phase short circuit and experiment on the automatic reclosing of the line adjacent to the short-circuit point in order to determine the maximum possible duration of a current-free pause. Obtaining the limiting time for tripping a three-phase short circuit and increasing it by introducing an automatic speed controller and selecting the controller parameters.
