Water supply network leakage loss control method
The invention discloses a water supply network leakage loss control method. The water supply network leakage loss control method comprises the steps of calculating the difference of the PRZ pressure at a most disadvantage point and required lowest pressure of a pipe network according to pressure data of PRZ pressure at the most disadvantage point, and then adjusting water outlet pressure of a water plant according to the difference, determining the optimization grade of DMA pressure regulation and control and determining whether DMA is suitable for pressure regulation and control or not according to flow and pressure monitoring results at a DMA inlet position, determining the optimization grade of DMA on the aspect of leakage loss monitoring according to flow monitoring results and pipe network length at the DMA inlet position and further determining pipe network maintenance and update schemes of all DMA. The water supply network leakage loss control method integrates a leakage loss control method based on pressure control and leakage loss control method based on pipe network maintenance and update, has the advantage of high pressure control effect and the advantage of thorough pipe network maintenance and update and meanwhile overcomes respective disadvantages.
