description: Tasks completed in the course of the work: 1. Investigation of processes occurring in the 330/110 kV power supply network. Selection of power electrical equipment: transformers, overhead power line wires, autotransformers, etc. 2. Performing an analytical calculation of the steady-state mode of the system based on the parameters of the selected equipment, as well as calculating the steady-state mode in the RastrWin3 software package. The mode of maximum and minimum loads, taking into account compensating devices, is also consid-ered. 3. Drawing up a replacement scheme for the electric power system. Calculation of currents and voltages of a two-phase short-circuit to the ground by the method of symmetric components relative to a given point in the replacement circuit. Con-struction of vector diagrams of currents and voltages at the short-circuit point based on the calculation results. Calculation of the same parameters in the ATPDraw "EMTP" software package with the corresponding dependency graphs. 4. Study of electromechanical transients occurring in the power system in the software package "Dymola". Checking the electric power system for dynamic stability under a given disturbance (two-phase short-circuit to the ground). Tak-ing measures to improve dynamic stability: adjusting the ARV coefficients. As a result of the choice of equipment, we calculated the steady-state operating modes of the power system during the maximum (daytime peak) and minimum (night minimum) loads using the means of reactive power compensation and the adjustment of the transformer RPN. The unbalanced short-circuit currents at the top of the ring network were calculated. We modeled the transients of a three-machine power system in the "Dymola" software package and obtained the value of the limit time for disconnecting a two-phase short circuit to the ground. Measures were taken to improve the dynamic stability of the system in the event of a three-phase short circuit.
