description: The topic of the final qualification work is "Analysis of steady-state and transient modes in 330/110 kV power system". This work is devoted to the calculation of power system modes with subsequent selection of equipment, calculation of short-circuit currents and calculation of dynamic stability. The tasks that were solved during the study are: 1. Selection of system elements such as transmission lines, transformers and generators. 2. Steady state analysis of the power system. 3. Calculation of currents and voltages under emergency mode of the system. 4. Elaboration of recommendations on increasing the dynamic stability of the system. Analysis of steady-state condition indicated the necessity of installation of compensating devices at loads to reduce voltage drops and achieve permissible values of voltages at loads. Batteries of static capacitors for reactive power generation were installed. However, they were disconnected in minimum load mode. The system failure mode, represented by an asymmetrical short circuit, was simulated and the calculation was performed in two different ways and the results were within the margin of error. When analyzing the dynamic stability of the system, it was found that the system with these parameters remains stable under a single-phase short-circuit, therefore, more severe emergency conditions were selected. A three-phase short-circuit was simulated and methods to increase dynamic stability were implemented for it.
