为解决城市排水泵站系统中存在的机泵运行效率低、泵水耗能大、综合节电效果差等问题,从对机泵进行调速实现拓宽机泵运行高效区域分析了泵站系统的节能机理,并提出进水池目标水位下,跟踪流量变化进行调速的优化控制方案,在泵站系统无污水溢出情况下,降低了泵站系统的能耗。 In order to solve the problems of low operating efficiency, large pump energy consumption and poor overall power saving effect in the urban drainage pumping station system, this paper analyzes the problems of pumping station system Energy saving mechanism and put forward the optimal control scheme for speed regulation under the target water level of the inflow pool and tracking the flow changes, which reduces the energy consumption of the pumping station system under the condition of no sewage overflow in the pumping station system.
