description: In this paper, a 220/110 kV power supply system is considered. Power equipment and wires cross-sections of power lines are selected and tested. The steady-state operation of the network, as well as currents and voltages for a double-line-to-ground fault have been calculated. The calculations have been carried out analytically and with suitable software. Vector diagrams for the short-circuit currents and voltages of all phases are plotted. Experiments to compare short-circuit currents and voltages calculations with and without active resistances in the calculation scheme elements were performed. The dynamic stability in the three-machine equivalent circuit is calculated and the short-circuit breaking time are determined and limit angle. The following short-circuit types have been considered: double-line-to-ground fault, three-phase short-circuit in a given point and at transferring the point closer to the generator, automatic reclosing of overhead line at double-line-to-ground fault in a given point. As a measure to improve dynamic stability, pulsed turbine off-loading was carried out.
