description: During the final qualification work, the analysis of the power supply system with a voltage of 500/220 kV was carried out. A selection of elements such as (generators, transformers, overhead lines) was made. They are used to calculate the established operating mode of the power system. The calculation was carried out both manually and with the use of the software RastrWin. Short-circuit currents were determined by the method of symmetrical components. In our case, we considered a two-phase short circuit (at the beginning of VL6). In the Dymola software, transient modes in power supply systems were calculated. Two-phase and three-phase short circuits were used as an example. The main goal was to find a time limit for disabling these short circuits so that our system would remain dynamically stable. Then measures were taken to increase dynamic stability, that is, to increase the braking zone and reduce the acceleration zone. The optimal solution in this power supply system is parallel electric braking, the essence of which is to connect the load (brake) resistances or change the resistances of some pre-selected circuit elements that affect the change in the load of generators.
