Coordination algorithm-based real-time water distribution method for channel system in irrigation region

Abstract

The invention discloses a coordination algorithm-based real-time water distribution method for a channel system in an irrigation region. The method comprises the steps of 1) performing water demand plan reporting according to water demands of water users in the irrigation region; 2) when a total water quantity in the irrigation region is less than a total water demand quantity of the water users,building a real-time water distribution scheduling model; 3) establishing a Hamiltonian function to work out optimal solutions of distributed water quantities of the water users; and 4) according to the optimal solutions, scheduling flow distributed to the water users and gate opening. The water quantity scheduling accuracy and timeliness are improved and the water resource effective utilization rate is increased.

Description

technical field [0001] The invention relates to the field of irrigation, in particular to a method for real-time water distribution of canal systems in irrigation areas based on coordination algorithms. Background technique [0002] The water supply in the irrigation area is mainly agricultural irrigation water, as well as domestic water supply, industrial water and ecological water supplement. The canal system in the irrigation area is composed of main canals, branch canals, bucket canals and other water delivery channels, which deliver water to the farmland area for irrigation. Most of the traditional water distribution scheduling is limited to the empirical dispatching method, which fails to solve the water distribution dispatching under the premise of the actual water distribution flow and demanded water flow, which is easy to cause waste of water resources and untimely water distribution dispatching. It is mainly reflected in: water distribution dispatching based on expe...

Most of the traditional water distribution scheduling is limited to the empirical dispatching method, which fails to solve the water distribution dispatching under the premise of the actual water distribution flow and demanded water flow, which is easy to cause waste of water resources and untimely water distribution dispatching. It is mainly reflected in: water distribution dispatching based on experience , the accuracy of water volume scheduling is low, which is easy to cause waste of water resources; the water allocation scheduling of water resources under hypothetical conditions cannot be effectively scheduled in combination with the actual water resources of the canal system, resulting in untimely water allocation scheduling; when water resources are limited, it cannot Effectively coordinate the effective distribution of living, production and agricultural irrigation water resources
