description: In this work, the design of the electrical part of the gas-and-oil IES with a capacity of 4x800 MW has been carried out. In the process of performing the work, a structural diagram was drawn up, for this, various schemes were considered in order to determine under which option there would be a minimum power flow through the autotransformer. Further, the choice of power equipment was made: generator, power transformers, autotransformer, auxiliary transformer, reserve transformer for auxiliary needs. The main wiring diagram and auxiliaries diagram have been selected. Calculations of the short-circuit currents required for the selection of switching devices have been carried out. The selection of switching devices was made, short-circuit currents were previously calculated at 5 points where they should be installed. To ensure reliable and uninterrupted power supply to consumers for the generator-transformer unit with a high-side voltage of 500 kV, a choice of relay protection was made. Further, the settings were calculated: differential protection of the transformer, longitudinal and transverse differential protection of the generator, overcurrent protection, distance protection, etc.
