【摘要】 本文对输油管道压力瞬变过程进行了分析，建立了管道压力实时模型，研制出输油管道的泄漏故障实时诊断系统的软、硬件，完成输油管道泄漏检测及定位的室内试验和现场试验。并结合管道瞬变模型法与负压波法建立多维判别法则，解决输油管道泄漏检测及漏点定位的问题。在理论上分析了以上两种方法的结合将有助于提高泄漏检测定位的准确性。更多还原

【Abstract】 Based on the analysis of pressure transient change within the oil transfer pipeline, a real time pressure model of oil pipeline is set up. Software and hardware of the diagnosing system for leak detection & location were developed and the indoor experiment as well as site test was performed. By combining the transient change model method and rarefaction wave method, the multidimensional rules to detect the leakage and locate the leak point were set up. Also, the combination of the two methods is proved theoretically redound to improve the veracity of leak detection and location.更多还原
