| 摘 要： | 为了提高管网连通可靠度,介绍了燃气管网在中介状态下工作的可能性,建立燃气管网"安全—中介—失效"3级连通可靠度模型,改进了燃气管网管段单元只具有有效和失效2种工作状态.对复杂的燃气管网多个环状网络系统,采用桥管段单元全概率分级分解模型,化为简单的混联系统进行燃气管网连通可靠度的向量求解.针对管段单元间的相关性,考察相关性参数对复杂燃气管网系统连通可靠度的影响,增加了燃气管网连通可靠度计算的可信度.

| Abstract: | To improve connectivity-reliability of gas pipeline network the possibility of gas pipe network with intermediate state before failure is expounded.Based on the improved two states with safety and failure of pipe unit,a three-stage connectivity reliability work mode of safety-intermediate-failure is established.Through adopting hierarchical exploded mode of full probability,multi-loop gas pipe network with bridge circuit can be broken down into several simple compound pipe systems for reliability vector solving.The influence of correlation parameter among pipe units to connectivity reliability of gas pipe network is considered and the trust in connectivity reliability calculation is increased in this paper. |

| Keywords: | gas pipeline network pipe network with bridge circuit connectivity-reliability reliability vector |
