description: Based on the results of the final qualifying work, the electrical part of a pulverized-coal condensing power plant with 4 generator-transformer units delivering electrical power to switchgears of two voltage classes 220 and 500 kV was designed. 1) a block diagram of the power plant was selected, the main diagram and the auxiliary power supply diagram were developed; 2) short-circuit currents on high-voltage switchgears, on the generator current pipeline and in the auxiliary system are calculated; 3) based on the calculated values of short-circuit currents, the selection of switching equipment and generator conductor was made; 4) calculation of electromechanical transient processes in the auxiliary power supply system, calculation of the success of self-starting, selection of cables for powering auxiliary motors was carried out. 5) the start time of the most powerful electric motor is determined. Based on the design results, the electrical part of a pulverized coal condensing power plant was developed.
