压力分布在线仿真泄漏检测系统
|
摘要
榆济天然气管道目前面临管道泄漏及其次生灾害的威胁,需要一套完整的泄漏检测方案为管道系统安全生产提供保障。针对大型复杂天然气管道系统缺乏干线计量及沿线压力测点众多的特点,采用国内某公司自主研发的基于在线仿真的压力分布泄漏检测系统,通过对比分析在线仿真压力和实测压力偏差分布实现管道全线的实时泄漏检测,持续监测管道系统的运行状态,及时发现可能出现的微小泄漏并确定其位置。结果表明:该泄漏检测系统不仅可用于实现大型复杂天然气管道系统的泄漏检测,还能发现仪表故障、站场异常操作等异常事件,突破了管道系统分段泄漏检测的限制,并可以对天然气管道泄漏进行动态监测,定位泄漏点。(图7,参22)
Yulin-Jinan Natural Gas Pipeline is currently in the danger of pipeline leak and its secondary disasters, so an integrated leak detection scheme is needed to ensure its safe operation. In view of the lack of trunk line measurement and numerous pressure measuring points along large-scale complex natural gas pipeline systems, the pressure distribution leak detection system based on on-line simulation developed by a domestic company was adopted to carry out the real-time leakage detection on the whole pipeline, monitor the running state of the pipeline system continuously and identify possible minor leaks and locate them in time by conducting comparative analysis on on-line simulation pressure and measured pressure deviation distribution. The results show that this leak detection system can not only be used to realize the leak detection of large-scale complex natural gas pipeline systems, but also identify abnormal events, e.g. instrumentation faults and station operation. What's more, it breaks through the limitation of sectional leak detection of pipeline system, provides the dynamic monitoring and location on natural gas pipeline leak.(7 Figures, 22 References)
