The choice of elements of electric power system was made: transformers and sections of power lines. After that, the steady-state calculations were made âmanuallyâ and with the help of RastrWIN software, and the modes of maximum and minimum loads were considered. Currents and voltages at single-phase short circuit on station buses were determined and vector diagrams were constructed. In the final part of the work, the dynamic stability of the system was investigated using the Dymola software. |
