description: The topic of the final qualifying work: The electrical part of a nuclear power plant with VVER-1000 reactors with a capacity of 4 * 1000 MW. The purpose of the work is to design the electrical part of the NPP that meets the conditions of economy, efficiency and reliability. When designing, based on the electrical data of the station in the task, the main power equipment was selected: generators, block step-up transformers, autotransformers, TON and BTON of the first and second stages of transformation were selected. The main scheme of electrical connections, the scheme of own needs is selected. A technical and economic analysis of the station was carried out. To select switching devices, switches, disconnectors, current and voltage measuring transformers, busbars, current lines and cables, three-phase short-circuit currents were calculated and equipment was checked in normal and emergency modes. The measuring transformers were also tested for secondary load. The composition of mechanisms and electric motors for their own needs was considered, an ON scheme was drawn up, the success rate of self-start was calculated and the start time of the most powerful ON unit from the working TON was calculated.
