后处理设施给水系统是后处理设施重要的公用系统,对后处理设施的稳定、安全运行至关重要。给水系统的可靠性需要深入分析,应用GO法进行了研究。获得了给水系统的平均故障概率、最小割集、重要度等可靠性指标。结果表明,给水系统的可靠性比较高,符合单一故障准则,二阶最小割集对系统故障的贡献最大,应该采取措施予以消除。进一步深入对比分析GO法与故障树法,结果显示,对于给水系统的可靠性分析,GO法有建模容易且图形简洁的优点。
Reprocessing Facilities The water supply system is an important common system for aftertreatment facilities and is essential for the stable and safe operation of the aftertreatment facilities. Water supply system reliability needs in-depth analysis, the application of GO method has been studied. Obtained the water supply system, the average probability of failure, minimum cut set, importance and other reliability indicators. The results show that the reliability of the water supply system is high and meets the single fault criterion. The second-order minimum cut sets contribute the most to system faults and should be eliminated. Further in-depth comparative analysis of GO method and fault tree method, the results show that, for the reliability analysis of water supply system, GO method has the advantages of easy modeling and simple graphics.
