description: The purpose of the work was the reconstruction and modernization of the power distribution scheme of the CHP, which was based on the existing Avtovskaya CHP (CHP-15). The modernization included a direct change and optimization of the power output scheme, replacement of outdated and outdated equipment with modern ones. In the course of the work, the scope of modernization of the Avtovskaya CHP (CHP -15) was initially established, the main power equipment to be replaced or upgraded was selected, the main circuit of electrical connections was developed and the circuit of the power plant's own needs was changed. Next, threeâphase shortâcircuit currents were calculated, on the basis of which switching devices were selected - switches and disconnectors, as well as current-carrying parts - complete shielded current lines and 35 kV CL for connecting transformers T-4, T-5 with ORU-35 kV. A complex of relay protection and automation of the generator - transformer unit operating directly on the busbars was also developed: possible damage to generators and transformers, as well as types of protection against them, were considered. The manufacturer of relay protection and automation devices was selected, a set of protections was formed and the protection settings were calculated.In conclusion, the main circuit of the electrical connections of the station, the protection distribution scheme for current measuring transformers and voltage measuring transformers, the design drawing of the gas-insulated switchgear 110 kV were created.
