Abstract:
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.
