Abstract

The given work is devoted to the study of the complex power supply system 750/330 kV, the choice of equipment, the calculation of currents of short circuit and the verification of dynamic stability. This work consists of four paragraphs: 1. The choice and verification of the equipment of the power supply system, generators, (auto-) transformers and power lines; 2. The calculation of the steady â€“ state operation mode of the power supply system analytically and the calculation of the modes of maximum and minimum loads of the system in the software package â€œRastrWin3â€; 3. The calculation of currents and voltages at a two â€“ phase short circuit to the ground on the second power line analytically (the method of symmetrical components) and in the software package "EMTP"; 4. The assessment of dynamic stability of the three-machine power supply system in the software package "Dymola". In the last paragraph, the following results were obtained: steady-state operation mode and limiting time for breaking a short circuit. Based on the results, measures aimed at increasing the dynamic stability of the system were selected and proposed.
