Topic of the work: «Selection of equipment and calculation of electrical modes of the 110/35 kV power supply system».The main task is to study the power supply system, including the analysis of steady-state and transient operating modes.In the process of completing the thesis, 4 sections were considered:Selection and verification of the main elements of the electric power system. Two-winding and three-winding transformers, sections of power lines, generators and generator transformers were selected.Calculation of the steady-state operation mode. This section included the calculation of the parameters of the electrical network, as well as the consideration of the steady-state mode analytically and using the «RastrWin» software.Calculation of currents and voltages of an asymmetric short circuit. A two-phase short circuit was modeled, the method of symmetric components and «EMTP» was used.Calculation of dynamic stability in the «Dymola» software environment. Determination of the cut-off time limit and the use of measures to improve the dynamic stability of electric power systems.    |
