In this final qualifying work, the electrical part of a nuclear power plant with VVER-1000 reactors with a capacity of 2x1000 MW was designed. The purpose of this work is to design the electrical part of a nuclear power plant using modern equipment and time-tested solutions for this type of power plant. In the process of performing the work, turbine generators, block step-up transformers, autotransformers for communication between switchgears 330 and 750 kV, as well as circuits of these switchgears for the output of generated electricity were selected. Based on the technical and economic analysis, the optimal structural scheme was selected. The calculation of three-phase short-circuits currents for the selection of circuit breakers, disconnectors, measuring current and voltage transformers, busbars, busbars, cables. Checking the equipment in normal and emergency modes has shown its suitability for operation. The following were developed: the main scheme of electrical connections, the layout of equipment on the territory, the design of the 330 kV switchgear. This work allows you to understand the electrical part of nuclear power plants, learn its features during design, which is a good experience for future work. |
