description: This work is devoted to the design of a 110/35 kV electric power system, followed by the calculation of the steady-state operation mode, modeling of an asymmetrical short circuit and analysis of the transient stability of this system. To achieve the set goals, the following tasks were solved: 1. Selection of the following elements of the EPS: generators, power transformers, wire sections of overhead lines. 2. Calculation of the steady-state operation mode analytically and using the "RastrWin3" program. 3. Calculation of currents and voltages of a two-phase short circuit at the site of damage analytically and using the "EMTP" program. 4. Calculation and analysis of the dynamic stability of the EPS using the "Dymola" program, followed by measures to improve it. As a result, the maximum and minimum steady-state operating modes of the projected power plant were obtained and optimized. Their optimization was carried out due to the installation of compensating devices and the use of the OLTC device of power transformers. The results of the two methods of calculating the simulated emergency mode are within the margin of error. When assessing the transient stability, the limit times of short-circuit disconnection were determined with appropriate measures to increase stability, as well as without them.
