摘要
采用基于软件系统的平台开发保护与监测系统时必须应对软件的固有共模故障问题,其安全认证是昂贵且复杂的工作。先进逻辑系统是西屋公司开发并通过NRC认证的新一代基于FPGA技术的1E级平台。为了能够应用该先进平台来开发保护与监测系统并降低取证的难度,基于该平台的特性、其在2个核电厂保护系统部分功能替换工程的实践以及核电厂保护与监测系统的典型功能需求,设计了一种基于ALS平台的保护与监测系统新的总体架构,并分析了该设计与DI&C-ISG-04要求的一致性。分析表明该设计满足安全系统数据通信的独立性和隔离要求,可应用于实际工程。
The software common mode failure is a critical issue to be addressed for the PMS developed with software based platform,such as Common Q or TXS. The licensing of the system is very expensive and hard usually. FPGA technology based ALS platform was designed by WEC and has been approved by NRC as the next generation 1E class platform for protection and monitoring system development for nuclear power plants. To facilitate the advantage of the most advanced platform for the PMS development and to relax the hard licensing jobs,based on the features of the platform and typical PMS function requirements,a new overall architecture with ALS for PMS is designed and the consistency with DI&C-ISG-04 is analyzed. The evaluation indicates the design meets the data communication independence and isolation requirements and can be referenced for engineering project.
