摘要  天然气管网系统是指由多条干线天然气长输管道及其配套储气调峰设施组成的、各子系统之间具有信息和天然气互联互通能力的大型基础设施。天然气管网系统作为连接天然气资源和市场的纽带,其可靠运行直接关系天然气的安全平稳供应。因此,有必要对天然气管网系统可靠性进行研究,保障我国公共安全和能源安全。其中,提出一套客观、明确的指标体系用以量化天然气管网系统的可靠性是管网系统可靠性研究的关键。本文归纳和总结了天然气管网系统可靠性研究成果,基于天然气管网的特征和功能,并结合管网可靠性研究的应用需求,将管网系统可靠性分为机械可靠性、水力可靠性和供气可靠性。基于此,提出三类可靠性评价指标,包括管网系统机械可靠性评价指标、水力可靠性评价指标和供气可靠性评价指标,分别用于表征系统正常运行能力、完成供气任务能力和满足市场需求能力。

Abstract

A natural gas pipeline network system is an example of large-scale infrastructure. It is composed of a number of long-distance natural gas transmission pipelines and their supporting facilities such as underground gas storages, with information and natural gas interconnection capabilities. As critical infrastructure connecting gas resources and markets, the security of gas supply is directly related to the safe and reliable operation of the natural gas pipeline network system. Therefore,it is necessary to study the reliability of natural gas pipeline systems to ensure public safety and energy security in China. An objective reliability index system is the key to quantifying the reliability of the natural gas pipeline network system. In this paper,by reviewing previous research into natural gas pipeline network reliability and combining the practical application requirements of the pipeline network reliability research, the reliability of natural gas pipeline network systems is divided into mechanical reliability, hydraulic reliability, and gas supply reliability based on the characteristics and functions of the natural gas pipeline network. Moreover, three types of reliability evaluation indicators are proposed, and are used to quantify the capacity of normal operation, the capacity of completing the required gas supply tasks, and the capacity of satisfying required demand.

Key words: natural gas pipeline network system; reliability evaluation index; mechanical reliability; hydraulic reliability; gas supply reliability
