摘要/Abstract

摘要： 核电厂数字化控制系统(DCS)的国产化工作是核电自主化战略的重要部分之一.为进一步提高其国产化水平，针对核电厂DCS设备研制过程中元器件的国产化替代问题进行了初步研究；对国产元器件的现状进行了分析，总结了目前核电厂DCS元器件国产化工作中面临的元器件门类不足、质量控制成本过高、选型信息缺失等问题.针对上述问题，首先参考武器装备、航空航天领域的元器件国产化经验，总结了元器件替代的一般方法；然后结合NB/T 2001标准，提出采用汽车级元器件的方案，并通过实施分级筛选策略实现质量与成本控制的平衡；最后提出加强研用双方合作，解决关键元器件的研制问题，为核电厂DCS元器件的国产化工作提供了可行的方案.

Abstract: The localization of digital control system (DCS) in nuclear power plant is an important part of nuclear power independence strategy. In order to further improve its localization level, the localization substitution of components in the development process of DCS equipment is preliminarily studied. And the current situation of domestic components is analyzed. The difficulties faced in the localization of DCS components in nuclear power plants are summarized, such as the lack of component categories, high cost of quality control and lack of information. Based on the experience of components localization in the field of weapon equipment and aerospace, the general methods of component replacements are summarized. Then according to the NB/T 2001 standard, the automotive-grade components are proposed to use as an alternative solution. By implementing the strategy of grading screening, the balance between quality and cost can be realized. At last, it is proposed to strengthen the cooperation between research and application, which can provide a feasible scheme for the localization of components in DCS of nuclear power plant.

Key words: nuclear power plant; digital control system (DCS); electronic component; localization
