description: As part of the final qualification work on the topic "Analysis of steady-state and transient modes in the 110/35 kV power supply system", an electric power supply system is being designed. The system design process is divided into four sections. In the first section, the equipment is selected according to the known data of the work option. Based on the value of the power and the load power factor, the power and generator transformers are selected, then based on the power factor of the power transmission lines and the value of the maximum active power of the selected transformers, the sections of power lines are selected. Based on the results of the first section, we make a table with a complete list of the above equipment. In the second section, the calculation of the steady-state calculation of the electric power supply system is performed first using formulas, and then compared with the result modeled in the RastrWin program. If there is a mismatch in the voltage level in some nodes, then either the RPN is used or compensating devices are added. In the third section of the paper, we consider a short circuit, the type of which is set directly by the supervisor. For this work, a two-phase short circuit is modeled using the EMTP program, and the current and voltage of the short circuit are manually calculated using the symmetric component method. The results are compared, and a conclusion is made. In the final section of the work, the electric power supply system is considered for dynamic stability. First, all the system parameters are reduced to the basic conditions in relative units in order to use the Dymola program. The analysis involves the system's response to strong perturbations. Such disturbances are two-phase and three-phase short circuits. Further, additional measures are introduced to improve stability - the use of three-phase reclosing of power line. Based on the results of all calculations and the selection of the correct settings and equipment, we have a system that meets all the requirements of stability.
