Abstract
The present invention introduced a method for detecting pipe bursts in water distribution systems based on pressure disturbance extraction, including following steps: (1) collecting and pre-processing monitored pressure data, and establishing a matrix of monitored pressures; (2) analyzing time-domain and frequency-domain features of the matrix of monitored pressures by Fourier transform, extracting disturbances, and generating pressure disturbances matrices; (3) identifying outliers in the pressure disturbances matrices by isolation forest algorithm; and (4) further identifying detected outliers by calculating and qualitative index A and quantitative index B and outputting a result of pipe burst detection. Compared with previous methods, the pipe burst detection method introduced in the present invention is accurate and reliable, and is more applicable to large-scale complex water distribution systems.
