description: The work is devoted to studying the electric power system 750/330 kV. The research set the following tasks: 
1) Selection of power equipment and cross-sections of power lines. 
2) Calculation of steady-state operation by two methods (manually and in the RastrWin3 software). 
3) Calculation of currents of single-phase short circuit at the beginning of the first line. 
4) Calculation of dynamic stability. 
Selection of the number and power of transformers and autotransformers was made according to their load coefficient in normal and post-accident conditions. The cross-section of power lines was selected according to the economic current density with subsequent verification of the long-term allowable current. 
During the calculation of the steady-state operation in the RastrWin3 software, the installation of compensating devices was carried out to ensure the required voltage values at the load nodes, as well as minimal losses of active power. 
Calculation of currents of single-phase short circuit was made by using the method of symmetrical components. Corresponding vector diagrams were plotted. 
Calculation of dynamic stability was made by using the Dymola software. Measures to increase dynamic stability were also proposed and implemented.
