description: In the work the design of the electrical part of the thermal power plant with the selection of the main equipment of the plant was carried out. On the basis of technical and economic analysis of two options, the optimal scheme of the station was selected. For the selected scheme, calculation of three-phase short-circuit currents in different points of the system was made. Based on the values of the obtained short-circuit currents and scheme parameters were selected circuit breakers, disconnectors, measuring current and voltage transformers. The current-carrying parts of the station with their thermal resistance and mechanical strength have been selected. Calculation of station auxiliary system, selection of circuit breakers, second stage transformers, cables. Check of auxiliary cables for thermal resistance and non-flammability. Calculation of successful self-starting and determination of start-up time of the most powerful auxiliary electric motor - drive of feeding electric pump. The following drawings were made: principal electric diagram of the station, auxiliary needs diagram and 110 kV switchgear section.
