This paper presents the electrical part of a nuclear power plant with VVER-1000 reactors with a capacity of 3x1000 MW. Methods for selecting the main equipment, the main wiring diagram, and auxiliaries are presented. The calculation of short-circuit currents for the selection of electrical devices and conductors has been carried out. Transient electromechanical processes in the auxiliary system are calculated. Evaluation of the success of self-starting of auxiliary electric motors has been carried out. The calculation of the start-up time of the main circulation pump has been made. Cables for auxiliary needs were selected and tested for thermal resistance and non-flammability conditions. |
