| 摘 要： | 泵站可用于田间配水、城市用水,多级泵站大多建在西北黄土高原地区,由于各区域用水分布不均,输水系统复杂以及运行管理等问题,多级提水泵站需要进行系统的优化调度。以某多级提水泵站为研究对象,当泵站在正常情况下运行时,即流量为6.1 m^3/s,对于泵站级间采用粒子群算法,优化结果与实际运行情况相比,各级泵站水位发生微调,在该流量下水位实现一个相对较好的组合,单位时间内可节约1.66%的能量,一年大约可节约98万kWh。优化后多级泵站从整体降低了能耗,在尽可能提高其运行效率、降低能耗的基础上,使其在安全、经济的情况下运行。

| Abstract: | The pumping station can be used for field water distribution and urban water transfer.Multistage pumping stations are mostly built in the Loess Plateau.Because of the uneven distribution of water use in each region,the complexity of water delivery system and operation management,multistage pumping stations need to be optimized.This paper takes a multistage pumping station as the research object.When the pump station is in normal operation(flow rate is 6.1 m^3/s),particle swarm optimization algorithm is used to optimize the pump station.Compared with the actual operation,the water level of pumping stations at all levels is slightly adjusted.At this flow rate,the water level can achieve a relatively good cooperation.It can save 1.66%energy per unit time.About 980000 kWh of electricity can be saved in one year.After optimization,the energy consumption of multistage pumping station is reduced.On the basis of improving operation efficiency and reducing energy consumption as much as possible,it can operate in a safe and economic situation. |
