Wiener model of pressure management for water distribution network

摘要

In this paper, the pressure management model of water distribution network (WDN) is established, which relies on the hydraulic law of the whole WDN, not the relationship between the pressure and flow based on the leakage. In view of the specific WDN, the configuration is pumped into a closed system with pressure control. And the pressure management model of WDN is divided into two modules by all the tanks which are extracted from the WDN. The two modules are linear dynamic module and nonlinear static module in series. A Wiener model is proposed to describe the nonlinear dynamic relationship of the pressure management model. Moreover, the theoretical data calculated by the Wiener model are compared with the real data generated by EPANET to show the effectiveness and high accuracy of our proposed modelling method.
