description: The topic of the final qualifying work: "Study of the modes of operation of power systems when joining the UNES of the energy district of Salekhard". This work is devoted to the research of perspective electric modes at connection of the isolated Salekhard energy district to the Tyumen energy system. Tasks that were solved during the research:Â Analysis of existing power balances of the power systems under study.Â 2. Analysis of reactive power balances of the Salekhard energy region and the Tyumen energy system in modes of winter maximum loads after connection to the UNES.Â 3. Research of perspective electric modes of operation during connection of the Salekhard energy region to the Tyumen energy system. The RastrWin software package was used in the work, where calculation schemes for winter maximum load modes were collected based on control measurements and consumption forecast. As a result of the analysis of existing and prospective capacity balances, it turned out that in 2021 the energy district of Salekhard is redundant, and in the period from 2023 to 2025 it is deficient. The analysis of reactive power balances showed the need for the use of compensating devices. The calculation of the maximum permissible flows of active power in controlled sections during the reception and delivery of power from the energy district of Salekhard was performed. An inspection of the power grid equipment showed that emergency shutdowns in the normal and repair circuits of the power system of Salekhard does not lead to current overloads of power transmission lines.
