description: In the final qualification work "Analysis of steady-state and transient modes in the 330/110 kV electric power system" different modes of operation of electric power system are analyzed. The choice of electrical equipment (generators, transformers, transmission lines) is made, the steady-state mode calculation is done manually and in the software package "RastrWin", voltages and currents of phase-phase short-circuit to ground are calculated manually and in the software package "EMTP", measures to improve transient stability are developed. According to steady state calculation results, to achieve voltages within permissible limits it is required to install static capacitors banks in a part of nodes with load. In the minimum load mode it is required to deactivate static capacitor banks and to regulate transformer ratios to achieve required voltages. The results of the asymmetrical short-circuit calculation manually and with the "EMTP" software package agreed with an error of up to 1%. As a result of the verification of assumptions that were used in the analysis of short-circuit currents, it was found that their use is acceptable, as they do not introduce a significant error in the calculations. In consequence of the analysis of the transient stability of the power system, it was found that at a two-phase short-circuit to ground at a given point, the system loses its stability. By means of electrical braking of generators it was possible to increase the transient stability.
