description: In this work, research was conducted of the electric power system 220/110 kV. First of all, selection and verification of electric power equipment was made, such as: generator, transformer and autotransformer, power lines. Transformers and autotransformers checked at the maximum rated load. The check was carried out for a continuous current when determining the cross section of the power transmission line.
In the second chapter, the normal (steady-state) mode of operation of the electric power system was calculated. Initially, an equivalent circuit and its parameters (active and reactive resistances, inductive conductivity of power lines) were drawn up. The calculation of a given power system was implemented twice: manually and using the RastrWin software. Manually we calculated voltage drops, power losses. Using "RastrWin" the calculation of maximum loads and minimum loads. 
The essence of the third chapter was to calculate the currents and voltages of an asymmetric (single-phase) short circuit. First of all, the power system parameters were brought to basic conditions, then an equivalent complex equivalent circuit was compiled for the forward and reverse sequence. The result of the third chapter was the determination of currents and voltages in the place of the short circuit and the construction of vector diagrams. The end of the work was a check for the stability of this power system to short circuits (dynamic stability). During this check, the time was determined at which the power system loses stability, and measures were taken to increase this time (increase dynamic stability).
