【目的】研究山丘区“两库三站”灌溉系统优化调度方法。【方法】针对山丘区干旱年份2座水库、3座补库泵站联合调度的问题,构建“两库三站”灌溉系统优化调度模型,以各灌区各时段灌溉缺水量平方和最小为目标函数,以系统年可供水量、补库泵站年可供水量、补库泵站提水能力、水库优化调度准则等为约束条件。采用基于试验选优的大系统分解协调方法求解优化调度方案。【结果】以干旱年份江苏省南京市六合区山湖水库和泥桥水库联合优化调度为例,与优选参数的常规调度方案相比,泥桥灌区灌溉缺水量由35万m3减少到0万m3,山湖水库弃水量由45万m3减少到0万m3,引提河道水量由403万m3增加到435万m3,山湖水库、泥桥水库的终止蓄水量由819万、145万m3增加到初始蓄水量847万、159万m3。【结论】采用基于试验选优的大系统分解协调方法求解优化调度方案,能有效减少水库弃水量,增加灌溉供水量,也能充分发挥补库泵站提水能力,减少补库泵站提水次数,此外,还可以实现对水库终止蓄水量特定取值的要求。 |

Abstract: |
【Objective】The optimal scheduling method of "two reservoirs and three pumping stations" irrigation system in hilly areas was studied.【Method】Aiming at the problem of joint operation of two reservoirs and three pumping stations in drought years in hilly areas, the optimal scheduling model of "two reservoirs and three pumping stations" irrigation system was constructed. the objective function was to take the minimum sum of squares of irrigation water shortages in each irrigation area and each period, and the constraints included the annual water supply of the system, the annual water supply of the pumping station, the water lifting capacity of the pumping station, and the optimal scheduling criteria of the reservoir, etc. The large system decomposition-coordination method based on experimental optimization was used to solve the optimal scheduling scheme.【Result】Taking the joint optimal operation of Shanhu Reservoir and Niqiao Reservoir in Liuhe District of Nanjing City, Jiangsu Province in dry years as an example, the result showed that compared with the conventional scheduling scheme of preferred parameters, the irrigation water shortage in Niqiao Irrigation District was reduced from 350,000 m3 to 00,000 m3, the amount of abandoned water in Shanhu Reservoir was reduced from 450,000 m3 to 00,000 m3, the amount of extracted river water was increased from 4.03 million m3 to 4.35 million m3, and the terminated water storage of Shanhu Reservoir and Niqiao Reservoir was increased from 8.19 million and 1.45 million m3 to 8.47 million and 1.59 million m3 of initial water storage.【Conclusion】The large system decomposition-coordination method based on experimental optimization is used to solve the optimal scheduling scheme, which can effectively reduce the amount of abandoned water in the reservoir and increase the amount of irrigation water supply. It can also give full play to the water lifting capacity of the pumping station and reduce the number of water lifting of the pumping station. In addition, it can also meet the requirements for the specific value of the terminal water storage of the reservoir. |
