Abstract Gas pipelines are prone to faults due to aging, corrosion, and external factors. Undetected faults can result in injuries, damage to properties, and environmental contamination. Several techniques have been developed to help detect faults, though each technique having pros and cons. This review is set out to identify research gaps related to fault detection and diagnostics under transient conditions and associated inputs for a robust design. A closer look at the available literature reveals that there is indeed more research required in terms of addressing pipeline-compressor-valve system, multiple fault scenario, uncertainty quantification, and multiphase condition.

瞬态条件下天然气管道基于模型的故障检测和诊断的最新进展

摘要 输气管道易因老化、腐蚀和外界因素而发生故障。未被发现的故障可能会导致人员受伤、财产损失和环境污染。已经开发了多种技术来帮助检测故障，尽管每种技术都有优点和缺点。本次审查旨在确定与瞬态条件下的故障检测和诊断相关的研究差距以及稳健设计的相关输入。对现有文献的仔细研究表明，在解决管道-压缩机-阀门系统、多故障场景、不确定性量化和多相条件方面确实需要更多的研究。
