description: In this work the electric power system of 330/110 kV was studied. For the system, a selection of equipment was made: generators, transformers, autotransformers, sections of power lines. According to the selected elements the steady-state mode of operation of the electric power system was calculated in two ways: manual calculation and calculation using the student version RastrWin3 program. In particular, the calculation of the computer mode was performed for two variations: the maximum load mode and the minimum load mode, which is characterized by a decrease in installed power by 40%. For each design case, optimization procedures were performed to ensure the required voltage quality for receiving loads. Also, the paper presents the calculation of a two-phase short circuit to ground. The result of this part of the work was the obtained numerical values of currents and voltages at the point of short circuit, as well as vector diagrams constructed according to the calculated values. In the last part, we studied the dynamic stability of the system using Dymola software and solutions have been proposed to improve this indicator.
