description: Work consists of four main chapters, also an introduction, conclusion and list of references. 
The first chapter made the selection and verification of the main power equipment: transformers, autotransformers, as well as the choice and verification of power lines. 
The second chapter contains the calculation of the parameters of the electrical network, the calculation of the steady state of the electrical network analytically and using the appropriate software. Using software simulated modes of maximum and minimum loads.
In the third chapter we use symmetrical component method for calculation currents and short-circuit voltages for a given type of asymmetrical short-circuit (single-phase short-circuit) is carried out. For clarity, vector diagrams are constructed.
The fourth chapter is devoted to the analysis of dynamic stability. In this part, a number of experiments are carried out: single-phase, three-phase short circuits and three-phase reclosure of a single-circuit line.
Ð¡onclusions are drawn on the work done in conclusion.
