摘要
干线天然气管道是我国重要的战略能源通道,其运行可靠性研究显得十分必要。基于国内外相关文献调研,结合干线天然气管道的工艺特点,对干线天然气管道运行可靠性的重点评价指标进行筛选,并给出计算方法;运用可靠性基本理论和统计学基本方法,提出一种针对管道单元及压气站单元的运行可靠性评价方法;运用可靠性框图,建立单元与系统之间的联系,运用故障树分析法确定系统的薄弱环节,最终提出干线天然气管道系统运行可靠性的评价方法。(图5,表2,参31)
Gas trunk line is the important strategic energy channel in China. Therefore, the reliability research is essential. Through coalescing related Chinese and foreign literatures, key reliability evaluation indexes are screened, and the calculation method is provided combining with the technological characteristics of gas trunk line. A reliability evaluation method for pipe unit and compressor station unit is proposed by using basic theory of reliability and basic method of statistics. The connection between the units and system is established by using the reliability block diagram and the weak link in the system is determined through fault tree analysis. Ultimately, a reliability evaluation method for main gas pipeline is put forward. （5 Figures, 2 Tables, 31 References）
