Leak localization in pipeline network

摘要

A method and system to localize a leak in a pipeline network include identifying a respective measured time at which an effect of a leak exhibits in a time-varying data signal measured by each of a plurality of sensors distributed along the pipeline network, each pair of the plurality of sensors defining a respective pipe segment therebetween. Estimating a time of occurrence of the leak based on the measured time associated with two or more of the plurality of sensors; and estimating a relative distance of a leak location from one or more of the plurality of sensors. Determining the leak location is based on the relative distance.

1. A computer-implemented method of localizing a leak in a pipeline network, the method comprising:
identifying a respective measured time at which an effect of a leak exhibits in a time-varying data signal measured by each of a plurality of sensors distributed along the pipeline network, each adjacent pair of the plurality of sensors defining a respective pipe segment therebetween; estimating, using a processor, a time of occurrence of the leak based on the measured time associated with two or more of the plurality of sensors; estimating, using the processor, a relative distance of a leak location from one or more of the plurality of sensors; determining, using the processor, the leak location based on the relative distance; and performing a delay model calibration during normal operation without the leak in the pipeline network, the delay model calibration determining propagation delay d of the time-varying data signal in both directions through each of the pipe segments of the pipeline network.
