Abstract  

A new leakage discharge analysis model based on fast independent component analysis (FastICA) algorithm was established in order to solve the problems of the traditional leakage discharge analysis models, such as low simulation accuracy, incapability of reflecting the uncertain relationship between leakage discharge and presssure head and so on. The model divided total water supply flow into actual consumed water flow and leakage discharge and considered them as two source signals. In the model, the total water supply flow and pressure head at the entrance were considered as two input parameters. The waveform information of two flows were obtained by separating source signals. The order of the source signals was determined by comparing the correlation coefficients. The real amplitude of leakage discharge was solved out according to the flow balance equation. Therefore, the leakage discharge was simulated in time series. For this model, the input parameters are easily getparms. It can effectively avoid the complexity of the relationship between leakage discharge and head pressure. Thus the simulation accuracy is high in the water distribution system with one entrance only. The model has been preferably applied in the node demand distribution of one water distribution network’s hydraulic model.

基于FastICA算法的物理漏损流量分析模型

为解决传统供水管网物理漏损流量分析模型模拟准确度不高、无法体现物理漏损流量与水头关系的不确定性等问题,基于快速独立成分分析（FastICA）算法构建物理漏损流量分析模型. 该模型将供水总流量划分为用水流量和物理漏损流量,并视为2个源信号.以供水总流量和管网入口处水头2个参数为输入参数,通过源信号分离获得2个流量的波形信息,通过比较相关系数确定源信号的顺序,通过水平衡方程确定物理漏损流量的真实尺度,实现物理漏损流量在时间序列上的模拟. 该模型输入参数易于获取且有效避免了物理漏损流量与水头关系的复杂性,在单水源供水管网中模拟准确度较高,并且在供水管网水力模型节点流量分配中得到了较好的应用.
