description: The theme of the final qualifying work: "Selection of equipment and calculation of electrical modes of a complex electric power system 750/330 kV".This work is devoted to the study of a complex electric power system, the calculation of the steady state of this system, as well as the analysis of transient processes that appear as a result of disturbances of various types.Â Tasks to be solved in the course of this work:Calculation of the parameters of the electric power system and the choice of electrical equipment;Analytical calculation of the steady state of the initial power system and calculation of the parameters of the steady state using the Â«RastrWin3Â» software package, considering the mode of maximum and minimum loads;Determination of voltages and currents of a single-phase short circuit analytically and using the Â«EMTPÂ» software package;Study of the dynamic stability of the power system under consideration in the Dymola software package and the choice of measures to increase the dynamic stability margin.As a result of the work, the electrical equipment of the electric power system was selected with the subsequent calculation of the steady state in two ways: analytically and in the RastrWin3 software package.Using the method of symmetrical components, the currents and voltages were determined during a single-phase earth fault on the high voltage buses (HV) of the G1 generator station. The obtained current values ââwere compared with the values ââobtained in "EMTP".At Dymola, a study was made of the electromechanical transients of the power system and the time limit for disconnecting a single-phase short circuit was determined. As measures to increase the dynamic stability of the power system, it was proposed: three-phase automatic reclosing (TAR), single-phase automatic reclosing (SAR) and sequential electric braking (EB).
