description: The final qualifying work is devoted to the study of the 330/110 kV power supply system. Tasks that were solved during the research: 1. Selection of the main equipment used in the studied electric power system 2. Drawing up a replacement scheme and calculating the steady-state regime 3. Short circuit simulation and calculation of currents and voltages at the short circuit point 4. Study of dynamic stability and measures to increase the stability of the system under disturbances RastrWin computing complex was used to calculate the steady-state mode. To do this, a replacement circuit of the electric power system was built in the complex and the parameters of the equipment were set. After obtaining the steady state, the necessary compensating devices were selected to increase and maintain the required voltage level. As a result of the calculation, a graph was obtained with power flows across the elements, voltage levels in the nodes of the system and the capacities of loads and generators. The Dymola computing complex was used in the study of dynamic stability. During the study, it turned out that initially the system has a small margin of stability and additional measures are required to increase it. To do this, the following measures were used: shutdown of one of the hydraulic units and pulse unloading of the turbine. As a result of the events, it was possible to achieve the necessary quality parameters of dynamic stability. In addition to the singleâphase short circuit, a three-phase short circuit was also carried out during the study - thus, the study turned out to be more detailed and detailed.
