【摘要】：在运核电站模拟仪控系统面临技术老化和物理老化的问题,采用数字化DCS技术对在运核电站通用仪控系统的大范围升级改造具有技术复杂、影响面广、投资大,项目执行周期长、单次实施时间紧(只能在机组大修期间实施)等特点。从改造必要性、仪控系统设计基准、数字化仪控技术特点、仪控系统功能分析、仪控系统安全分级、仪控系统架构方案,仪控系统数字化改造全生命周期各关键阶段的工作任务、仪控系统数字化改造风险分析等几方面对在运核电站模拟仪控系统数字化升级改造需重点关注的问题进行了初步分析和论述。在此基础上,结合国外核电站仪控系统数字化改造的经验和教训,对我国在运核电站模拟仪控系统的数字化改造升级策略提出建议。
[Abstract]:The analog instrument control system in Yunyun nuclear power station is faced with the problems of technology aging and physical aging. The adoption of digital DCS technology to upgrade the general instrument and control system of nuclear power station in transit has the characteristics of complex technology, wide influence and large investment. Long project execution cycle, single implementation time is tight (can only be implemented during the unit overhaul) and other characteristics. From the necessity of transformation, the design standard of instrument and control system, the characteristics of digital instrument and control technology, the function analysis of instrument and control system, the security grading of instrument and control system, the architecture of instrument and control system, The task of digitized transformation of instrument and control system in every key stage of the whole life cycle, In this paper, the risk analysis of digital transformation of instrument and control system is presented, and the problems that need to be paid attention to in digital upgrading of analog instrument and control system of nuclear power station are analyzed and discussed preliminarily. On this basis, combined with the experiences and lessons of digital transformation of instrument and control system in foreign nuclear power stations, some suggestions are put forward for the digital transformation and upgrading strategy of analog instrument control system in nuclear power stations in China.
