- Abstract:
- A new district metered areas (DMA) partition method was proposed to solve the problems of immaturity and overreliance on experience of DMA for urban water distribution network partition. The similarity calculation formula between two nodes was defined, and the DMA region was divided by spectral clustering (SC) algorithm, so as to minimize the length of partition boundary pipes (BPs) and the number of large flow pipes in the BPs. Under the condition of meeting the pressure limit of the pipe network, the optimal arrangement model of valve and flowmeter on BPs was established by taking the sum of node pressure standard deviation, comprehensive water node age and partition cost as the optimization objectives. The model was solved by multi-objective particle swarm (MOPSO) algorithm to obtain the Pareto optimal solution set, and the decision of multiple layout schemes was made by technique for order preference by similarity to ideal solution (TOPSIS). The method was applied to a real pipe network for DMA partition. This method successfully completed the DMA partition of pipe network, and played a significant role in aspects such as improving the hydraulic characteristics and water quality of pipe network and reducing the partition cost.
