Investigating the performance of transient model based leak detection system for liquid pipelines

加拿大的管道网络庞大，每天输送约300万桶原油。即使有广泛的联邦和省级监管，管道公司也采取了许多措施来维护和监控管道，以确保安全运营，但管道泄漏总是有可能发生的。输油管道泄漏可能导致重大的环境影响和巨大的经济损失，这突出了有效的泄漏检测的必要性，以促进对泄漏事件的快速反应。泄漏的发生会导致瞬变事件，其形式为沿管道双向传播的压力波。通过使用计算机模型分析管道系统的水力行为，可以检测到泄漏的存在。基于计算机模型的泄漏检测技术在能源管道行业中被广泛使用，但其有效性往往受到计算机模型准确再现真实管道系统的复杂性的能力以及不准确和不充分的测量数据的限制。

Canada's pipeline network is massive with approximately 3 million barrels of crude oil transported every day. Even with extensive federal and provincial regulation, and pipeline companies undertaking many measures to maintain and monitor their pipelines to ensure safe operations, there is always a possibility that a pipeline leak could occur. Oil pipeline leaks can result in significant environmental impacts and huge economic losses, which highlights the need for effective leak detection to facilitate fast response to a leak event. The occurrence of a leak causes a transient event, in the form of pressure waves that propagate in both directions along the pipe. The presence of a leak can be detected by analyzing the hydraulic behaviour of the pipeline system using a computer model. Computer model based leak detection techniques are extensively used in the energy pipeline industry but their effectiveness is often limited by the ability of the computer models to accurately reproduce the complexities of real-world pipeline systems, and by inaccurate and insufficient measured data.
