含支线调蓄的调水系统水库群联合调度

Joint operation of reservoir groups in water transfer system with branch storage-regulation

针对调水工程与其支线调蓄工程所面临的复杂水库群联合调度问题,以陕西省引汉济渭调水工程及其支线调蓄工程焦岩水库、玉带河水库构成的联合调度系统为工程实例,运用拓扑概化方式揭示了各水源之间的水利-水量联系,并由此构建了联合调度模型,采用协同粒子群算法求解了10 a长系列调度,提出了单一水库多目标供水方案,解析了耦合系统补给调水效果。结果表明:支线调蓄工程能够在均衡多目标供水效益的基础上,通过耦合系统有效增加补给调水量,显著改善调水过程。

For the operation problem of complex reservoir groups faced by the inter-basin water transfer project(IBWT) and its branch storage-regulation project(BSRP),taking the joint operation system consisted of the IBWT of Hanjiang to Weihe River and its BSRPs of Jiaoyan Reservoir and Yudaihe Reservoir as an example,the hydraulics and water yield connection between the water sources was revealed using topological generalization method.Then a joint operation model was constructed,and the long time series regulation of 10 years was solved by the collaborative particle swarm optimization(CPSO) algorithm.With this model,a multi-objective water supply scheme for an individual reservoir was proposed,and then the effect of IBWT and BSRP coupled system was analyzed.The results show that the BSRP can effectively increase the water supply and significantly improve the transfer process of the coupled system on the basis of balancing the multi-objective benefits.
