description: Topic: "Selection of equipment and calculation of electrical modes of the 500/220 kV power supply system". A small part of the power system with its generation and load nodes was calculated in the work. First of all, the main equipment was selected: generators, transformers and power lines. Then comparisons were made between the analytical calculation and the calculation in the RastrWin software package of the steady-state mode, in which the values coincided with some error. The mode of maximum and minimum loads was presented.Further, using the method of symmetrical components, currents and voltages were calculated at the point of a single-phase short circuit from below the ring network at a voltage of 220 kV, which were subsequently compared with the values obtained in the EMTP program.Since systems with large voltage classes have a small margin of stability, which was determined by the limit time of disconnection of the short circuit, an analysis of its dynamic part was performed in the Dymola software package. To increase the stability of the power system, an event was undertaken â parallel braking of the generator.
