description: During this work, the transient processes in the 330/110 kV power plant were calculated using analytical calculations and software modeling. Initially, the necessary equipment was selected (power transformers and AT, sections of power lines), so that the system could function clearly with the specified parameters in the source data. Then we calculated the steady-state mode in the EES, that is, the stresses in the nodes and the power flows in the branches. This manual calculation was compared with software modeling in RastWin, calculating the mode of maximum and minimum loads. We built a diagram of the EES in the form of graphics for greater clarity. In the further course of the work, we proceeded to the calculation of a single-phase short circuit at the beginning of the 330 kV overhead line with the corresponding vector diagrams. We confirmed the data on the transient process using computer modeling in the EMTP software package, making sure that the results are similar for the waveforms. In the end, using the Dymola software package, which uses the Modelica language, we modeled the emergency mode, analyzed various parameters and considered measures to improve dynamic stability (OAPV, Pulse discharge of the turbine).
