| Abstract: 【Objective】In this paper, through the study of optimal control of canal rotation irrigation group, to realize the efficient water distribution in irrigation area and provide a scientific basis for the work of canal water distribution.【Method】In this paper, the flow rate of lower canals and the number of rotational groups are taken as the decision variables. Taking the short total water distribution duration, the small distance between the most upstream and the most downstream canals in the same group, and the small water distribution duration difference of each canal in the same rotational group as the objectives, and considering the time constraints, the outlet state constraints, the canal overflow capacity constraints, and the water balance constraints, a multi-objective water distribution model is established, and the NSGA-II algorithm is used to solve the water distribution model. 【Results】The model in this paper is applied to Shipi East branch canal in BoJiLi irrigation area. The lower canals is divided into 9 rotation irrigation groups, and the water distribution flow rate and total water distribution time of the model meet the requirements; The model divides the adjacent canals into one round grouting group as much as possible and opens and closes them at the same time to facilitate the management to operate the gate.【Conclusion】The water distribution model in this paper can distribute water with large flow rate, short duration and less workload, and can provide support for water distribution in irrigation areas. |
