description: Based on the results of the final qualifying work, the electrical part of a two-transformer 110/35/10 kV substation was designed, connected to the 110 kV system by three overhead power lines and supplying consumers at voltage classes of 35 and 10 kV. During the design, a choice was made of the substation structural diagram, power transformers, auxiliary transformers, and switchgear diagrams. Using the RastrWin software package, the operating modes of the substation were calculated, the voltages on the busbars of switchgears and the power flows across the substation elements were determined. The work includes calculation of three-phase short circuit currents at 4 points of the substation, as well as calculation of single-phase short circuit current in the auxiliary power supply system. Based on the data obtained, switching devices, instrument transformers and current-carrying parts were selected. The developed substation is capable of reliably supplying consumers with electricity, and the equipment is resistant to prolonged exposure to heavy-duty currents, as well as to the thermal and electrodynamic effects of through short-circuit currents.
