A unified framework for pressure driven network analysis

Un cadre unifié pour une analyse des réseaux conduite par la pression

Résumé

Pressure-driven hydraulic computer models are often used to assess the operation of water dis-tribution systems with inadequate capacity or failures. However, theoretical problems occur when several subscribers are aggregated in a single node. In addition, some numerical problems and inadequate results have recently been reported. In this paper, the authors propose to consider explicitly integrity non-negative constraints for pressure. It is shown than demand at nodes is automatically reduced if the pressure is reduced. As a result there is no need to introduce a further relationship between pressure and consumption. An optimization method is applied to guarantee global convergence and a unified framework is set which includes both the proposed and conven-tional approaches. Links between the previous formulations and the proposed algorithm are clarified.
