摘要
采用故障树分析方法对城市燃气输配系统的故障树模型进行定性和定量失效分析。针对系统的事件发生概率不确定情况,将模糊数学引入到故障树分析方法,给出了输配系统的模糊故障树安全评估方法。计算表明,该方法用于输配系统的安全评估是行之有效的。
This article conducts a qualitative and quantitative failure analysis of the fault tree model of urban gas transmission and distribution system based on fault tree analysis.In accordance with the uncertainty of the event probability,it introduces fuzzy mathematics to the fault tree analysis and proposes the fuzzy fault tree safety assessment method of the transmission and distribution system.Practical results show that the method is effective when assessing the safety of the transmission and distribution system.
