description: Theme of final qualification work: âAnalysis of steady and transient conditions in the electric power system 750/330 kVâ.
 In this work, the choice was made of the equipment of the electric power system - power transformers, considering emergency overload by 40% over the rated current for the time of maximum loads and wire cross sections of power lines with subsequent verification according to technical conditions. 
The calculation of the steady-state operation mode of the elements of the electric power system "manually" and the variant calculations using the software in which the maximum and minimum load modes were implemented. In order to maintain the required voltage level in the system and optimize the mode, the tap numbers of on-load tap changers of transformers and autotransformers were selected, and a list of compensating devices was determined. 
The currents and voltages are calculated for a two-phase short circuit to ground using the method of symmetrical components and based on the simulation in a specialized software package of the same emergency disturbance, the dynamic stability of the power system under consideration is analyzed. The short-circuit breaking time has been determined and measures to increase stability have been proposed.
