当管网中任一节点的水头或压头低于要求值时，称管网处于欠压状态。这些压力不足节点的需求不能完全满足。为了使分析简单，通常假设需求得到充分满足，而不管可用的压头如何，这种方法被称为需求驱动分析。为了简单起见，需求驱动分析在过去得到了极大的关注，并且几个计算机软件包随时可用于分析正常运行的供水管网。另一方面，水头驱动或压力驱动分析可以有效地用于分析压力不足的情况，因为这些方法考虑了每个节点处的水头流量关系。本文提出了一种压力不足的分析算法，使用广泛使用的需求驱动的分析为基础的求解器。通过基准配水模型对算法进行了验证。
AbstractA water distribution network is said to be under pressure-deficient condition when hydraulic-head or pressure-head at any of its nodes fall below the required level. The demands at these pressure-deficient nodes cannot be fully satisfied. To make the analysis simple, it is generally assumed that the demand is fully satisfied irrespective of the pressure-head available and this approach is referred as demand-driven analysis. For simplicity, demand-driven analysis received great attention in the past and several computer packages are readily available for the analysis of normal operational water distribution network. On the other hand, head-driven or pressure-driven analysis could be effectively used to analyze the pressure-deficient condition as these methods consider the head-discharge relationship at every node. This paper presents a pressure-deficient analysis algorithm using the widely used demand-driven analysis-based solver. The proposed algorithm is validated through benchmark water distribu...
