Pressure variation characteristic research for water supply network based on leakage variation analysis

In order to analysis the relationship between pressure variation and the leakage, the fundamental state equation of water supply system is built on the basis of measuring pressures and their variation in water supply pipes. At the same time, the basic relations of flow rates disturbance and pressure status variation are derived. Measuring the ΔP with online monitoring technology and building the inverse problem for leakage location based on intelligent optimization to find the leakage points in water supply network. Through real-time monitoring of demand and pressure variations, the leakage model is able to be built, which will supply technical support to diagnose the failure points in water supply network effectively.
