description: The process of designing of the electrical part of a coal-fired condensing power plant with six units of 200 MW was described in this article. According to the initial data, a feasibility study was carried out and the main scheme of the station was subsequently chosen. The main equipment was also chosen: generators, block transformers, autotransformers. The three-phase short-circuit currents were calculated at the characteristic points of the circuit (at switchgear and generator terminals), and the main switching equipment was also selected: switches, disconnectors, current-carrying parts, current and voltage transformers. A separate chapter was devoted to the power plants own needs. Within the framework of this chapter, the short-circuit currents on the auxiliary sections were calculated, switching devices were selected (the input switch to the auxiliary section, the switch of the most powerful connection). And also current-carrying parts were chosen: cables: the most powerful, medium power and the most low-power - electric motors. Finally, the electromechanical transient processes that take place in the motors of the auxiliary system were analyzed. Then the start-up time of the most powerful unit (feed pump) was calculated. In addition, for some units (feed pump, circulation pump and smoke exhauster), methods of capacity control were chosen. The result of the work is data on each of the selected devices that correspond to the parameters of the scheme and network. The main scheme of the station, its layout, as well as a drawing of a 110 kV switchgear were also designed.
