| 摘 要： | 为解决给水管网中的水质传感器位置优化布置问题,以污染发生至传感器首次监测到超过临界污染物质量浓度的期望监测时间最短为目标,提出监测突发性或者蓄意污染的管网传感器优化选址模型.以Anytown管网为例,利用EPANET软件模拟扩展周期非稳态水力水质条件下节点污染物质量浓度变化,通过编制程序与EPANET交互得到传感器监测时间,在此基础上设计求解该优化模型的混合粒子群算法.提出的优化模型及求解方法对保护管网安全、降低用户饮用被污染水的风险具有一定意义.

| Abstract: | In order to optimize the sensor placement in water distribution systems,a method to detect accidentally or intentionally injected contaminants is proposed,aimed at minimizing the elapsed time from the attack to the detection of the contaminations by sensors.The concentration of node contaminants under unsteady hydraulic and water quality conditions in extended period is simulated using EPANET with the example of Anytown water distribution system.Then a code is programmed to interact with EPANET to compute the detection time,and a hybrid PSO algorithm is designed to solve the placements of sensors.The method and algorithm proposed in the paper can help to protect drinking systems and reduce the risk on public health caused by accidental or intentional injection of contaminants. |
