In this work, the speech was about the study and analysis of operating modes and dynamic stability of a system of voltage class 220/110 kV.To do this study, it was important to start with the choice of equipment (transformers, autotransformers, and transmission line cross-sections), and then after that, the calculations of the steady state operation mode were performed. These calculations were done âmanuallyâ (using the analytical method) and using the software âRastrwinâ. In Rastrwin, the modes of maximum and minimum loads were found.Currents and voltages were also calculated for a single-phase short circuit at the output of TG2 (generator transformer-2), vector diagrams were plotted, and an emergency mode (fault regime) was simulated using the software EMTP and the results were compared.A little later, by the end of the work, the dynamic stability of the system was analyzed in the software âDymolaâ based on oscillograms. |
