description: This work is devoted to the study and analysis of steady-state and transient modes in the electric power system (EES). In the course of the study, several tasks were solved: 1. Selection of the main elements of the EPS. 2. Study of the steady-state regime. 3. Calculation of currents and voltages of single-phase short circuit. 4. Evaluation of the transient stability of the system based on numerical simulation of electromechanical transients and the proposal of measures to improve it. From the analysis of the steady-state modes of maximum and minimum loads, the need for the installation of compensating devices (CU) in load nodes, as well as changes in the transformation coefficients of transformers and autotransformers to achieve the required voltage level on loads was revealed. The calculation of currents and voltages of an asymmetric short circuit was performed by the method of symmetric components and in the EMTR software package. The level of transient regenerating voltage at the site of damage was checked, which satisfied the level required according to regulatory documents. Evaluation of the transient stability of the system revealed the need to improve it. To do this, a pulse turbine unloading was applied at the generator closest to the place of occurrence of a short circuit, which significantly increased the dynamic stability of the system.
