Topic of the final qualifying work: "Expansion of the electrical part of the NPP with power units with reactor units VVER-1200". The work is devoted to the development of a project for the electrical part of the Tianwan NPP, located in the Jiangsu province of the People's Republic of China. 6 power units with VVER-1000 reactors are in operation and two additional power units with VVER-1200 reactors are under construction.Tasks that were solved during the work on the dissertation: Study of the installed capacity structure of power plants in China and a comparative description of the types of nuclear reactors used. Analysis of the power distribution scheme and development of a project for the electrical part of the NPP in connection with its expansion. Study of the power supply scheme and the composition of the mechanisms for auxiliary needs of new power units with VVER-1200 reactors. In the course of designing, the main NPP electrical connection diagram was developed taking into account the parameters of the electrical equipment in operation and the characteristics of new power units. The technique was studied and the calculation of the three-phase short circuit currents for the designed circuit was performed, the ELK-14 and ELK-3 switchgear for voltages of 220 and 500 kV, the HECS-100 and HEC-7 EGRU for generator circuits, K cabinets were selected and tested for thermal and electrodynamic resistance. -105 with HD4/GT type vacuum circuit breaker for 10 kV auxiliaries switchgear. When choosing conductors, preference was given to cables with insulation made of cross-linked polyethylene (PvPu) and conductors of the TEKNP type. Additionally, the work presents a diagram of the power supply of auxiliary loads, the composition and distribution of mechanisms between sections. |
