Abstract:

由于不同水源汇入及分出等的交替作用与影响，多水源、多用户联通构成的多元汇入和分出的输调水系统运行是水量、水质混合及时空演变的过程，为量化不同节点及引出目标的水源构成和水质指标时变状态，研究建立了多元输调水系统动态水指标解析模型。模型以输水系统干网和各汇入、分出口及调蓄工程为研究范围，以沿程实时水量组成、水质因子为研究对象，提出系统多元动态水量与水质指标解析计算方法。以南水北调中线总干渠河南段为示例，应用模型得到干渠各节点、分出口的各水源水量构成、水质因子等指标成果，经分析可为制定科学合理的调度方案、实现预报预调或水量统计核算提供技术支撑，从而提高多水源联合调度的管理水平。
Due to the alternating effects and influences of multiple sources recirculation and flow cross-mixing, multi-source water, multi-user communication, multi-input and separate water transfer system opera-tion is the process of the amount of water, water quality mixing and water quality evolution. The water source composition of different nodes and the extraction targets and the dynamic water quality index need to quantify. An analytical dynamic water index model is developed for multi-source water delivery system in this study. The model takes the main stream, the import and export, storage projects as the research scope, the real time composition of water and the change of quality along the path as the research object. Taking the Henan section of the Middle Route of the South-to-North Water Transfer Project as an example, the application model is used to obtain the results of the water source flow composition and water quality factors of each node and branch of the main canal. It provides technical support for the realization of predictive pre-adjustment or statistical accounting, improving the management level of dispatch operations.
