description: During this project, a design of the electrical part of a nuclear power plant with three PWR-440 reactors and six generator units with a power output of 220 MW each was developed. An optimal structural diagram of the power plant was chosen, in this case, the "4-2" scheme. The selection of the main equipment such as generators, transformers, and autotransformers was made. Calculation of normal and emergency operating conditions was performed. The choice of overhead power transmission lines and their quantity was made. For the internal needs of the power plant, the composition of electric motors and mechanisms was determined, based on which the main and backup transformers for internal use were selected. The main electrical connection diagram and the diagram for internal use were developed. Short-circuit current calculations and thermal impulse calculations were carried out, based on which current-carrying parts and switching devices were selected. Additionally, a self-start test of the internal use motors from the backup transformer and the calculation of the startup time for the most powerful unit was performed. The selection of primary and secondary electrical equipment was done under applicable regulations and government standards governing the design, construction, and operation of electrical installations and power facilities. The graphical part of the project was executed using the "AutoCAD" software. The outcome of this work is the design of the electrical part of the nuclear power plant, including an explanatory report with supporting calculations and drawings of the main electrical connection diagram of the power plant.
