description: Based on the results of the final qualifying work, the electrical part of a pulverized coal condensing power plant was designed with six generator-transformer units that deliver electrical power to switchgears of two voltage classes of 220 and 500 kV. During the design, a choice of power equipment (generators, transformers and autotransformers) was made; 1) the block diagram of the power plant has been selected, the main circuit and the auxiliary power supply circuit have been developed; 2) calculated short-circuit currents at high voltage switchgears, on the generator current duct and in the auxiliary system; 3) on the basis of the calculated values of short-circuit currents, the choice of switching equipment and generator current duct was made; 4) the calculation of electromechanical transients in the power supply system for auxiliary needs, the calculation of the success of self-starting, the choice of cables for powering auxiliary motors were made. Based on the design results, the electrical part of the pulverized coal condensing power plant was developed.
