description: In the graduate qualification work of bachelor "Design of the 220/110 kV district electric power system" the design of the electric power system was carried out based on the analysis of various modes of its operation. Firstly, the excerpt of elements of the power system was made, the list of which includes transformers, cross-section of overhead power lines, generators as well as generator transformers. After the selection, the calculation of the steady-state operation of the system was carried out, firstly using Â«RastrWinÂ» software package, and then manually. Secondly, voltages and currents of a two-phase short circuit on high-voltage side of a generator transformer at a 220 kV powerplant were calculated using the method of symmetrical components, and then using "EMTP". Finally, measures to increase transient stability were considered. Based on the calculation of the steady-state mode, it was concluded that it is required to implement static capacitors to maintain voltages within the permitted limits. The results of calculating the asymmetric short circuit manually and using "EMTP" were similar with an error of approximately 5%. Based on the results of studying the transient stability of the power system, it was practically proved that with a two-phase short circuit at a given point, the stability of the system was lost. By shutting down one hydrogenerator, the transient stability of the system under study was increased.
