【摘要】：随着城镇化水平的不断提高,城镇居民和企业的用水量在不断增加,城镇供水网点也在不断增多,城镇供水管网规模也在不断扩大。由于用水需求形式的变化,山西吕梁某供水公司原有供水系统难以满足新形式下水资源的供应,需要对供水系统进行改造和升级。在分析了原有供水系统网点和供水管网的铺设情况下,进行了供水系统总体升级改造规划。在规划中重点完成对二次加压站系统的升级改造工作。针对原有加压站系统在新增供水网点的情况下加压能力不足的问题,完成了加压站系统的硬件升级设计,包括传感器,PLC,加压泵和变频器的选型以及相关电路的设计。针对原有加压站系统恒压变流量的调度方案能耗过高的问题,研究了新的调度方案。选择变压变流量的一级调度策略,在此基础上进行了加压站二次调度方案的研究,建立加压站系统模型,利用人工蜂群算法,以加压站最小泵群总功率为目标函数,各加压泵并联高效运行为约束条件,进行二次加压调度方案的寻优求解,得出加压泵群总功率最小的二次调度方案,并与遗传算法寻优过程进行了对比。依据调度方案,结合现场实际状况,完成PLC程序的设计,包括主程序以及报警,数据处理,调度方案执行等子程序的设计。针对原有网络通讯稳定性差的问题,设计了基于GPRS网络的通讯改造方案,进行GPRS-DTU的设备选型,完成了PLC,DTU和监控中心之间的通讯设置,实现了监控中心固定IP的入网改造,提升供水系统的通讯稳定性。根据改造方案,完成了监控中心的改造设计、组态开发和数据库的建立以及各个参数的匹配连接,并设计了供水系统的监控界面以及与之对应的功能。
[Abstract]:With the improvement of the level of urbanization, urban residents and the consumption is increasing, urban water supply network is also increasing, urban water supply network scale is expanding continually. Due to changes in demand for water in the form of the original water supply system of Shanxi Lvliang water company to meet the new form of water supply, the need for transformation and the upgrade of the water supply system. In the analysis of the original water supply system laying outlets and water supply network, water supply system of overall upgrade planning. To complete the upgrade work station system pressure to the two in the planning focus. Based on the original pressure station system pressure capacity shortage in new water supply outlets under the condition of complete the pressure station system upgrading of hardware design, including sensors, PLC, design and selection of pressure pump and frequency converter and related circuit. Based on the original pressure The problem of high energy consumption scheduling scheme of constant pressure variable flow station system, study the new scheduling scheme. Choose a scheduling strategy of variable flow, on the basis of the research station two times scheduling scheme for pressurization of the pressurizing station to establish system model, using artificial bee colony algorithm, the minimum pressure station pumps for the total power the objective function, the pressure pump in parallel and efficient operation as constraint conditions, optimize solution seeking two pressurized scheduling scheme, the pressure two times scheduling scheme with minimum total power pump group, and the searching process of genetic algorithm are compared. According to the scheduling scheme, combined with the actual situation of the scene, to complete the design of the PLC program, including the main program and alarm, data processing, design and execution scheduling scheme based on the original network communication subroutine. The problem of poor stability, the design of communication scheme based on GPRS network, GPRS-DTU The selection of equipment, completion of the PLC, between the DTU and the monitoring center set up communications, realized the transformation of fixed IP network monitoring center, to enhance the stability of communication of the water supply system. According to the scheme, completed the renovation design of the monitoring center, connecting, development and the establishment of database and configuration parameters, and the design of the monitoring interface of water supply the system function and the corresponding.
