The aim of this work is to design the electrical part of a nuclear power plant with VVER-440 reactors. Tasks that were solved during the design: 1. The choice of the structural scheme of the power plant and the main electrical equipment. 2. Calculation of short circuit currents at characteristic points of the circuit. 3. The choice of switching devices, current-carrying parts, measuring current and voltage transformers. 4. Development of drawings of the main circuits of electrical connections, the scheme of own needs, a plan and a section of one of the high voltage switchgears. In the course of work, the initial data were calculated and the generators, block step-up transformers, autotransformer, working auxiliary transformers and backup auxiliary transformers were selected based on them. A technical and economic analysis of the circuit options was carried out and on the basis of it a structural scheme of the power plant was selected. Short-circuit currents are calculated for the selection of switching devices and current-carrying parts. Also, the scheme of own needs and scheme of high voltage switchgear circuits were selected. As a result, the choice of electrical equipment for this power plant was made, the main circuits of electrical connections, plan and section of one of the switchgears with a filling circuit were drawn up.
