description: This work considers the stages of design and development of the electric power system. In the course of the work the following issues were considered: 1. Calculation of the steady-state mode of normal and repair schemes of the existing power system using the software package RastrWin. 2. Selection of equipment for connection of a new consumer and calculation of the steady-state mode considering this connection. 3. Calculation of three-phase and single-phase short-circuit currents in the EMTP-ATP software package. 4. Calculation of dynamic stability of the system by means of modelling of electromechanical transients and development of measures to increase the level of dynamic stability. The result of this work was the following: â¢ calculation of steady state; â¢ implementation of technical measures to improve power quality; â¢ selection of equipment for connection of a new consumer; â¢ recalculation of the steady-state mode considering the new connection; â¢ calculation of short-circuit currents, based on which circuit breakers were selected; â¢ during the dynamic stability calculation, the maximum time required for short-circuit tripping was determined; â¢ realization of impulse turbine unloading, which increased the maximum short-circuit tripping time.
