description: In this work, the main characteristics of the energy systems of the Republic of Sakha (Yakutia) and the Amur region were considered and analyzed: the main power plants, the forecast of electricity demand, the main planned inputs of consumers and capacities, reactive power balances. Then the option of upgrading the power distribution scheme of the Neryungrinskaya power plant was considered in connection with the construction of two new power units, and the main power equipment necessary for their operation was selected. Next, the three-phase short-circuit currents on the 220 kV switchgear and on the generator buses were calculated. According to the obtained values, the choice of switching and measuring equipment was made. Also in this work, the calculation of the steady-state regime of winter maximum loads in the RastrWin3 software package was performed, the flows of reactive power and voltage in the circuit were analyzed. In the last part of the work, the maximum allowable active power flows were calculated.
