沭水东调工程跨流域水库群联合供水研究

在分析日照市沭水东调工程特点的基础上,以城市供水量最大、水库弃水量最小为目标建立了多目标跨流域水库群联合供水调度模型。同时,将遗传算法嵌套于长系列变动时历法中,对工程涉及的沭河流域青峰岭、小仕阳、峤山水库以及傅疃河流域日照水库进行联合供水调算,探讨沭河流域各水库的可调限制库容和日照水库需水动态限制库容等调水指标。结果表明,水库群联合供水较各水库单独供水可增加利用沭河水量939万m3,反映了水库群联合调度有助于充分挖掘沭河流域各水库的供水潜力,对解决日照市区供水缺口十分有利。

Research on Joint Water Supply of Multi-Reservoirs of Water Diversion Project from Shuhe River Basin to Futuanhe River Basin

The joint water supply regulation model of multi-reservoirs of the water diversion project from the Shuhe River Basin to Futuanhe River Basin was proposed according to the characteristics of the project. The model was based on two objectives including the maximum urban water supply and minimum surplus water. The model was solved using the Genetic Algorithm and the long-series time series method, and it was then used to determine the joint water supply of the Qingfengling, Xiaoshiyang, and Qiaoshan reservoirs in the Shuhe River Basin and Rizhao reservoir in the Futuanhe River Basin, which can provide the allowable limit reservoir storage of each reservoir in the Shuhe River Basin and dynamic water requirement limit of Rizhao reservoir in the Futuanhe River Basin. The results showed that the joint water supply regulation of multi-reservoirs can increase the water supply volume of 9.39 million cubic meters in the Shuhe River Basin compared with the water supply regulation of single reservoir, which suggested that the joint water supply regulation can improve the water supply potential of each reservoir in the Shuhe River Basin and therefore solve water shortage problem in the urban area of Rizhao.
