Discussion on Interval Water Balance Dispatching Model of Pumping Station Group System for Water Lifting Irrigation:A Case Study on Jingdian Phase Ⅱ Project
High-lift irrigation projects are mainly distributed in water-deficient areas of northwest China,playing a vital role in addressing the production and domestic water demands for local people.In high-lift,multi-cascade and large-flow irrigation projects,water balance regulation of pumping stations is the focus and challenge in project operation and dispatching management.Taking Jingdian Phase II Project as an example,we analyzed the reasons for interval flow change during operation based on the characteristics of pumping station group system,and proposed the calculation method of interval flow change,as well as the selection of water balance adjustment method and adjustment time for pumping station group.Furthermore,the water balance dispatching model of pumping station group was established.The research findings provide reference for project dispatching management.
