摘要

供水管网运行状态的准确把握

对供水管网的健康监测与诊断至关重要

而监测点压力是管网运行状态最重要的标志之一。提出用于供水管网监测点压力在线预测的EMD（经验模态分解）与自回归模型相结合的方法

并对EMD组合模态所蕴含的物理意义进行了阐述。通过一实际供水管网中某监测点压力的在线预测与实际监测值的比较

验证了方法的有效性

此方法可提高城市供水管网健康的在线监测与诊断的效率。

Abstract

Accurate estimation of operation status of a water distribution system is essential to health monitoring and diagnosis of the water distribution system

while the water pressure is the most important indicator of the operation status.This study proposes a method

combination of EMD（Empirical Mode Decomposition） method and AR model

for online forecast of the pressure at monitoring stations in a water distribution system.The effectiveness of the method is verified by the comparison between the forecasting of the pressure in a water distribution system and the monitoring data.This study provides an effective way for online health monitoring and diagnosis of a water distribution system.
