description: This work is devoted to the study of the 110/35 kV power supply system. The following tasks are to be solved in this paper: 1. Selection and verification of electric power equipment suitable for this power supply system. 2. Calculation of the steady-state operating mode by the analytical method, as well as using the Â«RastrWin3Â» software package. 3. Calculation and modeling of an asymmetric short circuit using analytical calculations and the "EMTP" software package. 4. Study of the power supply system for dynamic stability, selection of measures aimed at increasing stability. As a result of the work, equipment was selected that ensures reliable operation of the electric power system in the mode of maximum and minimum loads. Based on studies of the dynamic stability of the system, it was decided to take measures to improve it. The use of the turbine speed controller made it possible to achieve a stable operating mode with finite perturbations of the system.
