A method for locating pressure-related leakage in a water supply network

Abstract

A method for locating pressure-related leakage of a water supply pipe network proposed by the present invention comprises the following steps: S1, constructing a simulation model of the water supply pipe network as a microscopic model; S2, monitoring the water flow state of the water supply pipe network in real time, collecting the Water flow parameters of real-time pressure data and flow data of each node in the network; S3. Attach the current collected water flow parameters to the microscopic model, establish a microscopic hydraulic model for simulating the transient water flow state of the water supply network, and establish a real-time SCADA database It is used to store the water flow parameters collected in real time; S4, combined with the real-time data in the SCADA database, the water flow parameters on the micro-hydraulic model are updated in real time to obtain the dynamic hydraulic model. In the present invention, in combination with steps S1-S4, the dynamic hydraulic model is obtained as the input object of the EPANET-PDLD model by carrying out physical simulation to the water supply pipe network and implementing real-time monitoring of pressure data and flow numbers at each node in the water supply pipe network, thereby through The EPANET‑PDLD model calculates and locates regional leaks in water distribution networks.

Description

technical field [0001] The invention relates to the technical field of water supply pipe network monitoring, in particular to a method for locating pressure-related leakage of a water supply pipe network. Background technique [0002] At present, the leakage monitoring of the pipeline network system often only relies on checking the leakage point where the pipe burst accident occurred, and then takes remedial measures after the pipe burst occurs. However, these leakage points have existed for a long time before the pipe burst accident usually occurs, and thus caused a large amount of water resource loss and economic loss. In addition, once a pipe burst accident occurs, it will often cause a large amount of waste of water resources, economic losses and even bad social impact. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a method for locating pressure-related leakage of a water suppl...
