description: This work is devoted to the calculation of steady-state parameters of an electric power system (EPS), the calculation of short-circuit currents and voltages, the analysis of transient stability of the EPS. The solved tasks are: 1. Selection of EPS elements. 2. Calculation of steady-state operating modes of EPS. 3. Calculation of currents and voltages of asymmetrical short-circuit. 4. Estimation of transient stability of the system based on numerical modelling of electromechanical transients. 5. Development of measures to improve the level of dynamic stability. The work was carried out using analytical methods of calculation and specialised software systems "RastrWin", "ATP-EMTP", "Dymola". As a result, the EPS given by the teacher was analysed. The steady state parameters of the EPS were calculated, and decisions were taken to optimise these parameters. Phase-phase-to-earth short circuit currents and voltages were calculated. The transient stability of the system was analysed and decisions were taken to improve the transient stability of the EPS.
