description: This work is devoted to the analysis of the structure of the power supply system for the auxiliaries of power units of nuclear power plants with VVER-1200 reactors, as well as the obtaining of skills in calculating and choosing electrical equipment designed to solve the tasks set for this system.
The tasks that were solved in the work:
1. Bringing the rationale for the separation of a single power supply system into separate, but interconnected small systems;
2. Analysis of the composition of elements in each of the small power supply systems;
3. Definition of methods to make the choice selection of the electrical equipment.
In the work, the separation of the power supply system into small systems was considered. For each of these systems, its purpose and detailed description were given. On the example of one of the systems, calculations of equipment loads, as well as short-circuit currents in alternating and direct current systems were presented. These calculations made it possible to make a preliminary selection of type for a part of electrical equipment. Short-circuit currents were calculated using the MathCad 15 software.
As a result, part of the work on the design of the entire power supply system for the unitâs own needs was presented. Based on this work, further calculations can be made that will allow a preliminary analysis of the costs of this system in the construction of the latest nuclear power plants with VVER-1200 reactors.
