description: During the final qualification work, the analysis of the 110/35 kV power supply system was made. Work was also carried out on the selection of elements of this system (transformers, overhead lines). Based on them, the established mode of the power system was calculated. The calculation was performed using two methods: manually and using RastrWin software. The short-circuit currents at point 5 (the beginning of VL6) were determined by the method of symmetrical components. In the Dymola software, transient modes in power supply systems were calculated. The main goal was to find the time limit for disconnecting short circuits so that our system would remain dynamically stable. Then measures were taken to improve dynamic stability. The optimal solution in this power supply system is to configure the ARV, the essence of which is to select the generator parameters to reduce the attenuation time.
