description: This work is devoted to the calculation of the modes of the electric power system (EPS) with the subsequent choice of equipment, the calculation of short-circuit currents, as well as the study of dynamic stability and the implementation of measures to improve it. Tasks that were solved in the course of this work: 1. Implementation of the selection and verification of power equipment in the electric power system. This is the choice of generators, power transformers and communication autotransformers, as well as wire cross-sections in power lines. 2. An analysis was made of the steady state operation of the power system, which included the determination of power flows and voltages in the design scheme. Also, the calculations of the modes of maximum and minimum loads were carried out using the RastrWin software package. 3. Using the method of symmetrical components, the calculation of currents and voltages in each node in the short circuit (SC) mode was made. Further, the same values were obtained using the EMTP software. 4. A study on dynamic stability, which includes the development of measures to increase the limiting time of short circuit disconnection. In this work, pulse braking of the generator served as this measure.
