description: The first stage of this work consists in the selection of main electrical equipment: generators and generator transformers, power transformers and autotransformers, wire sections of overhead power lines. After that, the selected equipment was checked according to the operating conditions in normal and post-emergency modes. At the next stage, the steady-state network operation was calculated analytically and using the RastrWin 3 software package. The results showed that to maintain the required voltage in the nodes and ensure optimal power flow, it is necessary to adjust the RPN devices of transformers, as well as install compensating devices. Next, the magnitude of the currents of a two-phase short circuit to earth was calculated using the method of symmetric components. The results obtained were compared with the data obtained with a similar calculation in the EMTP software package. The results differ by less than 5%. At the last stage of the work, an analysis of the dynamic stability of the system in question was carried out, which showed the need to apply measures to increase dynamic stability. To do this, the automatic frequency control setting and pulse unloading of the turbine were applied.
