Електрична частина атомної електростанції потужністю 2200 МВт з реакторами типу ВВЕР-440

Abstract

In the first part, a feasibility study of the project is made. In the electrical part, the calculation of electric load graphs has been performed, the power and auxiliary equipment has been selected, the structural scheme of the station, the schemes of the open switchgears 500 kV and 220 kV, as well as the auxiliary circuits have been selected; Switching equipment, busbars, measuring transformers, overvoltage arresters, batteries, as well as calculation of lightning protection and grounding device of ORU-500 kV. The selection of the relay and the settings of the protection trip have been made. The system of reliable power supply for consumers of the NPP own needs is considered. The automated control system of the technological process of the power plant is considered. In the economic part of the project, the cost of the generated electricity is determined taking into account depreciation charges, fuel costs, wages and other costs.
