摘要
针对现有定位方法在天然气输送管道泄漏点定位时存在定位误差大,影响后续应急抢修的问题,提出基于压力梯度法的天然气输送管道泄漏点定位方法。结合天然气输送管道泄漏时压力与流量的变化特点,判断管道是否泄漏。在此基础上,利用压力梯度法计算管道泄漏点的具体位置,并做出定位预警。天然气输送管道泄漏点定位对比实验结果表明,压力梯度法的定位误差较低,定位精度较高,更具有实际应用价值。
Aiming at the problems of large positioning errors and subsequent emergency repair of natural gas pipeline leakages,a method based on the pressure gradient method was proposed to locate the leaks of natural gas pipelines.Combined with the natural gas transmission pipeline leakage pressure and flow rate change characteristics,whether the pipeline leakages can be determined.The pressure gradient method was used to calculate the specific location of the pipeline leakage point and to make a positioning warning.Comparative experimental results of natural gas pipeline leakage point localization show that the pressure gradient method has lower localization error and higher localization accuracy,which is more valuable for practical application.
