description: The topic of the final qualifying work: "Analysis of steady-state and transient modes in the 500/220 kV power supply system".This work is devoted to the study of steady-state and transient modes of operation in each power supply system with specified basic parameters.In the course of this work, several tasks had to be solved. Based on them, the main equipment was selected, such as transformers, autotransformers, overhead lines, generators, and generator transformers. The next task was to calculate the steady-state operation of the system with some adjustments to ensure the maintenance of the required voltage level in the load nodes. A model of the system was also built in the Rastr software package. Next, the analysis of a single-phase short circuit was carried out and the values of short-circuit currents and voltages were calculated by the analytical method and using the EMTP program. The last task was to design a system in the Dymola program and determine its dynamic stability. It turned out that with a single-phase short circuit, the system retains its stability until a time greater than the standard time of disconnecting the switch, considering the action of the URS. Next, a more severe mode was considered â a three-phase short circuit and, based on this type of short circuit, the dynamic stability of the system was increased by using parallel electric braking.
