Application research of model-driven based adaptive scheduling in water distribution systems
With the increasing demand for refined management of water supply enterprises,re-quirements for water supply dispatching are also increasing.In this paper,the adaptive optimal scheduling method of water supply network based on hydraulic model was studied.By establishing hydraulic model and water quantity prediction model,the mathematical model of optimal schedu-ling was established based on genetic annealing simulation search algorithm.At the same time,combined with cluster analysis of working conditions,the computational complexity of search algo-rithm was greatly reduced.The generation efficiency of optimal scheduling scheme was improved.The adaptive scheduling system of water supply network was realized.In addition,the system was connected with the plant station control system to complete the automatic scheduling control.The automatic plant station and pipe network optimization scheduling was realized.Based on the actual production conditions of FY Water Division of Shenzhen,the water supply pressure in the area be-came stable.The overall distribution energy consumption was reduced by about 3％.The genera-tion time of the system scheduling scheme was not more than 40 s.The automatic execution time of the scheduling instruction was less than 30 s.The operation effect was remarkable,which effec-tively improved the scheduling efficiency and improved the quality and efficiency of water supply scheduling.
