description: This work is devoted to the design of the electrical part of a condensation power plant with predetermined generator power. Tasks to be solved in the course of work: 1) The choice of generators, transformers and autotransformers. 2) Choice of the main circuit of electrical connections, circuit power supply of their own needs. 3) Calculation of short circuit currents. 4) Choice of switching devices, measuring transformers of current and voltage. 5) Choice of busbars, cables, conductors, flexible wires, reactors. 6) Selection of current transformers according to the relay protection requirements. 7) Recommendations formulation for the relay protection of the unit. In the course of work on the final qualification work, the choice of electrical equipment necessary for the operation of the CPP with a capacity of 2500 MW was made. The most cost-effective main circuit of electrical connections was chosen, in which three units are connected to 220 kV power grid and two blocks are connected to 500 kV power grid. The main equipment consists of turbogenerators 800 MW and 300 MW, 400 MVA transformers on a 220 kV power grid and 1000 MVA transformers on a 500 kV power grid, and 267 MVA autotransformers. 220 kV power grid is made according to the scheme with two working and one bypass busbar systems. Switchgear 500 kV is made according to the scheme with two busbar systems and three switches for connection.
