Design And Study On The Direct Current Motor Control Center In Passtive Nuclear Power Plant

As the clean energy has been developing quickly in China,the proportion of the nuclear energy is also increasing in the total energy industry structure.Nowadays,in the scope of the nuclear power plants under construction,the passive advanced pressurized water reactor(PWR)technology,which meet the technical requirements of the third generation nuclear technology,has been used in Sanmen of Zhejiang Province and Haiyang of Shandong Province.And the passive advanced pressurized water reactor(PWR)technology is one of the most advanced nuclear technologies on the world.With the design and construction of the new technology,some new systems and equipments should be used in the nuclear power plants.The direct current(DC)motor control center is one of the new developed equipments.Based on the study of DC motor control center and DC motor operated valves,the sizing methods and design requirements of DC motor control center and DC motor operated valves are shown by establishing model,calculating and analyzing the parameter,then make sure the qualification and testing requirements.By verify by testing,a complete set of theory and related computational analysis methods will be established,then summarize a set of effective equipment design,type selection and research methods.And the theories will lay a solid foundation for future similar equipment selection and design method.
