| 中文摘要 | 供水系统中取水泵站的变频运行属于变频变压供水方式。EPANET为模拟供水系统提供了通用的框架,其中的水泵模型可以用来模拟各种工况下的水泵运行。水泵的外特性曲线、水泵转速及转速模式决定了水泵变频运行的模拟精度。通过联合应用EPANET内的水泵模型和压力破除阀模型,建立了供水系统中变频变压供水方式的模拟方法。将此方法应用于模拟我国南方某城市原水系统取水泵站的变频运行。经过模型校核及验证,结果表明该方法可以较为准确地反映此取水泵站系统的运行状况。; The operation mode of pumping station with variable frequency pumps(VFP) in water supply system is similar to the variable pressure mode with VFPs.EPANET provides a common framework to simulate the water supply system,which is realizable to model the operation of pumps in various kinds of conditions.Pump characteristic curve,pump speed and speed pattern are the key elements that determine the accuracy of the simulation in variable frequency mode.By combining the pump model with pressure breaker valve model in EPANET,a methodology was developed to simulate the variable pressure mode with VFPs in water supply system.A case study was conducted on one pumping station in raw water system of a city in South China.Through model calibration and validation,it showed that the model performed relatively accurately on representing the operation status in the pumping station system.; 国家高技术研究发展计划(863)项目(2007AA06A413); “十一五”水体污染与治理重大专项课题(2009ZX07425-006) |
