Improvement of Leak Detection Method for Petroleum Refining Pressure Pipeline Using Variational Mode Decomposition
This paper introduces improved variational mode decomposition to study the leakage detection method of petroleum refining pressure pipeline,aiming at the problem that the leakage location of petroleum refining pressure pipeline is quite different from the actual one.The single end leakage position of petroleum refining and chemical pressure pipeline is located,and the detection signal is enhanced with improved variational mode decomposition,and the instantaneous change of signal energy tracking and leakage detection are realized.The comparative experiment proves that the new detection method can realize the accurate location of the oil refining and chemical pressure pipeline leakage and stability.
