科学合理的输水控制策略是保障长距离调水工程安全平稳运行的基础，根据控制策略实现向各分水口门供水计划的目标。在总结现有输水调度控制研究成果基础上，通过结合调度运行实际，综合考虑目标水位控制的鲁棒性、水位降幅的约束性、渠道上下游水情的统筹性因素，对输水调度控制策略进行了改进，提出了基于流量变化、水位变幅相耦合的实时调度控制策略。根据流量变化对渠段进行水量平衡分析，实施宏观控制，同时根据水位及其变幅实施微观调控。模型应用于南水北调中线渠段水位调整典型工况，通过渠首至测试断面坟庄河节制闸之间，约1100km的输水调度，成功实现了坟庄河节制闸前运行水位按需求降低0．5m的目标，此过程中保持了其他渠段运行平稳。而传统控制策略由于未统筹考虑上、下游水情和水位降幅限制，测试时出现坟庄河节制闸前水位骤降，而其下游水位骤增的不利情况。

英文摘要：

Scientific and reasonable water conveyance control strategy is the basis for ensuring the safe and stable op- eration of long-distance water diversion projects. According to the control strategy, the goal of water supply plan to each sluice is realized. On the basis of summarizing the research results of the existing water conveyance dispatch con- trol, combining with the actual operation of the dispatch, considering the robustness of target water level control, the constraint of water level drop and the co-ordination of upstream and downstream water regimes, the water conveyance control strategy is improved. The real-time dispatch control strategy based on water flow change and coupling water lev- el-amplitude is put forward. According to the change of flow, the water balance analysis and macro-control are carried out, and the micro-regulation is implemented according to water level and its amplitude. The model is applied to the typical condition of water level adjustment in the channel section of Middle Route Project of South-to-North Water Di- version in China. The water level in front of the control sluice of Fenzhuang River is successfully reduced by 0.5 m ac- cording to the requirements through the long water conveyance dispatch of about 1 100 km between the channel head- work and the test section, and other channel sections keep running smoothly. Owing to that the traditional control strategy does not consider the upstream and downstream water regimes and water level drop limit, the water level in front of the control sluice of Fenzhuang River suddenly decreases, and its downstream water level greatly increases during the tests. The validity of the proposed model is verified through case studies.
