摘要
确保分输站功能可靠是保障天然气长输管道正常供气的基础,目前尚未发现针对天然气长输管道分输站功能可靠性的定义与评价方法。目前针对油气站场的可靠性方法一般基于"二态假设",一定程度上与实际情况不符。基于此,本文根据实际情况,定义了天然气长输管道分输站的功能可靠性;应用多状态系统可靠性评价方法,提出了分输站的功能可靠性评价方法,构建了其功能风险分析模型。
To ensure reliable delivery stations is a foundation to ensure the normal supply of natural gas transmission pipeline, has not yet been found for long distance gas pipeline station definition and evaluation method of functional reliability. The oil station general reliability method based on the ＂two state hypothesis＂, to a certain extent inconsistent with the actual situation based on this, according to the actual situation, the definition of natural gas distribution station function reliability of pipeline; reliability of multi state system evaluation method, put forward the distribution function method for reliability evaluation of station, establishes the function model of risk analysis.
