description: The topic of the final qualification work: "Calculation of steady modes, short circuit currents and dynamic stability in the electric power system 330/110 kV".This work is devoted to the calculation of steady state, short circuit currents and dynamic stability in the electric power system 330/110 kV. The work contains the main sections: selection of equipment and line conductor cross-section, calculation of the electric power system mode analytically and using RastrWin software package, calculation of short-circuit currents analytically and using EMTP software package, calculation of dynamic stability using Dymola software package.Â In the first section, the selection of generators, transformers, wire cross-sections of power lines are carried out. The second section contains the calculation of the parameters of the equivalent circuit, the analytical calculation of electric power system sections, as well as the calculation of the mode using RastrWin. In the third section of this work, the currents and voltages of a single-phase short circuit are calculated using the method of symmetrical components, as well as by equivalenting the circuits of each of the sequences. Next, the calculation is carried out using the EMTP program. The obtained values ââof currents and voltages of a single-phase short circuit are compared, and the calculation error is calculated. In the last section of the work, the equivalent circuit parameters are calculated using Dymola software package, obtaining a steady state, finding the maximum short circuit duration at which the system remains stable. Further, several measures are applied to increase the dynamic stability of the system (automatic reclose, ASR). The results obtained in the Dymola software package are presented in the form of graphs.
