【摘要】：针对现有管道泄漏检测技术在管道微小泄漏检测和油品泄漏损失计算方面存在的不足,基于流体动力学和容量守恒原理,开发基于VPL(Visual Pipeline)的输油管道实时泄漏检测系统。建立管道模拟平台,通过组态编辑器、图像界面、管道工作室和SCADA接口,开展输油管道实时泄漏检测、定位与分析,实现管道实时泄漏检测、报警,以及泄漏量的定量计算。现场测试结果显示,所开发的输油管道泄漏检测系统最小泄漏检出率为0.7%,泄漏点定位精度为96.96%,泄漏量计算准确率为94.42%。研究结果表明:基于VPL的输油管道实时泄漏检测系统漏报、误报率低,检测定位精度较高,尤其对于微小泄漏优势明显;同时,该系统能够实时定量计算油品泄漏损失,可以用于输油管道泄漏检测与应急辅助决策。
[Abstract]:Aiming at the shortcomings of the existing pipeline leak detection technology in the detection of pipeline leakage and the calculation of oil leakage loss, a real-time leak detection system for oil pipeline based on VPL(Visual pipeline is developed based on the principle of fluid dynamics and capacity conservation. Through configuration editor, image interface, pipeline studio and SCADA interface, the pipeline simulation platform is established to detect, locate and analyze the pipeline leakage in real time, to realize pipeline real-time leak detection, alarm and quantitative calculation of leakage volume. The field test results show that the minimum leakage detection rate of the developed leak detection system is 0.7, the accuracy of leak location is 96.96, and the accuracy of leakage calculation is 94.42. The results show that the real-time leak detection system based on VPL has the advantages of low false alarm rate, high accuracy of detection and location, especially for small leakage, meanwhile, the system can calculate oil leakage loss in real time and quantificationally. It can be used for oil pipeline leakage detection and emergency decision.
