description: This work is devoted to the design calculation of the electrical part of a pulverized coal condensing power plant with five power units with a capacity of 300 megawatts each. The work consists of 76 pages and contains 34 tables and 19 explanatory figures. Keywords: KES, transformer, main circuit of electrical connections, technical and economic analysis, switchgear circuit selection, short circuit current, equipment selection, self-service system, non-ignition check, thermal stability check, busbar, long-term permissible current, transformer, switch, disconnector, self-start, performance control. In this work, the selection of the main equipment of the pulverized coal condensing power plant was made, the analysis and selection of the block diagram and the circuit of switchgears were made. Then, based on the selected circuit, the short-circuit currents at the characteristic points were calculated and the corresponding switches, disconnectors, busbars, current lines, cables and measuring current and voltage transformers were selected. For the system of own needs of the power plant, the selection of transformers of the first and second stages, the calculation of short-circuit currents on the sections, as well as the selection of switches, disconnectors and cables to the motors of mechanisms is also made. In addition, for the most loaded section, the calculation of the success of self-starting from the working and backup transformer of own needs was made, and for the most powerful engine, the calculation of the start â up time was made. The result of the work is a project of a pulverized coal condensing power plant, which, with appropriate refinement, can be used in the design and construction of an operating station of this type.
