针对某核电厂某型数字化仪表控制系统(DCS)的反应堆保护系统(RPS),分析其RPS功能和结构,提出图形化自动建模的需求。根据需求设计开发专用的可靠性分析辅助软件,能实现对RPS安全功能可靠性分析过程的图形化组态,可创建、修改和保存组态图,并具有组态方案自动分析、故障树信息自动生成和导出等功能。
A reactor protection system (RPS) for a certain type of digital instrument control system (DCS) in a nuclear power plant is analyzed, and its RPS function and structure are analyzed. The demand of automatic graphical modeling is put forward. According to the requirements of the design and development of dedicated reliability analysis aided software, RPS safety functions to achieve the reliability of the graphical analysis of the configuration process, you can create, modify and save the configuration diagram, and has a configuration program automatically analyze the fault tree automatically Generate and export and other functions.
