Selection and testing of equipment, namely the cross-sections of wires of power lines and power transformers. 2. Calculation of the steady-state operating mode of the elements of the electric power system, performed analytically and in the specialized software RastrWin on a computer; 3. Calculation of two-phase short-circuit currents in the middle of the sixth overhead line analytically and using the EMTP calculation program. Creating a vector diagram of currents and voltages at the place of damage. 4. Assessment of the dynamic properties of the system. Numerical modeling of electromechanical transients. Organization of a number of emergency measures and analysis of their effectiveness.
