Detection and Location of Pipeline Leak Based on Multiscale Correlation

Abstract:

In the paper, firstly establishes the pipeline system model based on the principles of correlation analysis, and determines the correlation characteristics of pipeline flow and pressure. Secondly multi-scale analysis is introduced into dynamic system processing. A leak detection method is shown with the multiscale correlation analysis, and is compared to the residual correlation analysis; it overcomes two the mistakes with different nature, such as too much interference or loss of leakage signal details. Finally through the actual data verification, the methods suitable for mutation signal, but slowly changing signals need to find another method.
