In the model research and development work of the 3th nuclear power plant of Hualong-Ⅰ, the electrical major has carried out many important original research and development designs. Among them, the Common Distribution System of the electrical main wiring has carried out a series of fruitful innovative work. Firstly, the design concept of the Common Distribution System in the M310 2nd+ unit is briefly described, and its operation mode under different working conditions is analyzed;Furthermore, in line with the principle of not reducing reliability, in terms of automatic switching of main and auxiliary power supply, manual switching of backup power supply, design of multi-power key interlocking system, according to the needs of model research and development,a variety of Common Distribution System solutions are proposed;by comparing the advantages and disadvantages of each solution, a solution that meets the requirements of the third generation of Hualong-Ⅰ nuclear power plant is finally determined. The required, safe and reliable power supply design. Finally, the main aspects of the design of the Common Distribution System are systematically summarized, in order to provide reference for the subsequent design work.
