摘　　要：以某自来水厂的二级泵房为研究对象,设计泵组智能化控制系统,实现自来水厂智能化控制的需求,提升智能化运行水平。系统包括泵组优选模型和能效评估模型。基于该厂历史运行数据,对水泵特性曲线进行校核,采用遗传算法建立了泵组优选模型。同时,通过效率和配水单位电耗的计算,对泵组能耗进行实时评估。所建的泵组优选模型可根据具体应用场景对目标函数进行相应约束。通过改进初始化种群,可有效地提高算法的求解速度,实现二级泵房实时智能化控制。现场应用结果表明,通过该系统的优化调度,二级泵房泵组的配水单位电耗降低了17.4%、效率提高了5.6%、泵组运行效率不低于80%,节能效果较好。该系统适用于水厂泵房的优化控制,对泵站的节能降耗起着指导性作用。Taking the secondary pump room of a water supply plant as the research object,the intelligent control system for pumping group is designed to realize the demand of intelligent control of water supply plant and improve the level of intelligent operation.The system includes a pump group preference model and an energy efficiency evaluation model.Based on the historical operation data of the plant,the pump characteristic curve is calibrated,and the pumping unit preference model is established by genetic algorithm.At the same time,the pumping unit energy consumption is evaluated in real time through the calculation of efficiency and water distribution unit electricity consumption.The built pump group preference model,with corresponding constraints on the objective function according to the specific application scenarios,can effectively improve the solving speed of the algorithm by improving the initialized population,and realize the real-time intelligent control of the secondary pumping station.The field application results show that through the optimal scheduling of this system,the water distribution unit electricity consumption of the pumping unit in the secondary pumping house is reduced by 17.4%,the efficiency is improved by 5.6%,and the pumping unit operating efficiency is no less than 80%,which is a good energy-saving effect.The system is applicable to the optimal control of the pump room of the water plant and plays a guiding role in energy saving and consumption reduction of the pumping station.
