漓江实时补水优化调度研究

以漓江三期补水工程体系为研究对象,对漓江实时补水优化调度进行研究。首先基于马斯京根流量演算法建立了供水水库群放水和控制断面需水的定量响应关系,在此基础上提出考虑河道水流演进滞时和生态需水要求的漓江水库群联合补水实时优化调度模型及相应的调度规则,并通过约束处理技术使模型转化为能通过线性规划求解的问题。实时优化调度模型在漓江流域的应用结果表明:斧子口、川江、小溶江、青狮潭、五里峡、思安江六库联合调度,可以使特枯年份的供水日保证率达到94%以上。研究对维持漓江河道健康、提高通航保证率以及旅游经济效益具有重要的意义。

Real-time water2ssupply optimal operation in Li River Basin

Cho osing the thir d2phase w ater2tr ansfer pr oject as the research object, w e studied the r eal2time w ater2tr ansfer o ptimal operatio n in Li River Basin. First ly , w e built the quantitative r esponse relationship betw een the release of the w ater2supply res2 er voirs and w ater demand of the contr ol sect ion based on Musking umcs f low a lg orithm. Then we pr oposed a real2t ime w ater2 transfer optimal o per atio n model and co rr esponding operating rules fo r the r eser vo irs gr oup o n Li River, w hich to ok into co nsid2 er ation the water flow evo lutio n delay and the ecolo g ical water demand. T hr ough co nstr aint2handling t echniques, w e tr ansfo rmed the model into a question which could be so lved by linear programming. The application results showed that the joint operation of the six reservoirs on Li River ( including Fuzikou, Chuanjiang , Xiaorong jiang, Qingshitan, Wulix ia and Sicanjiang reservoirs) could raise the wa2 ter2supply daily assurance rate to abo ve 94% in especially dr y years. This study has important significance fo r maintaining a healthy riv er channel, increasing navigation assurance rate, and impro ving eco nomic benefits of to urism on Li River.
