Research On Optimal Operation Of Multistage Pumping Stations In Donglei â…¡ Yellowriver Puming Irrigation Project

This article studied the model of optimal operation of water supply by multistage pumping stations in DongLei II Yellow River Pumping Irrigation Project (Erhuang), which based on the study of analyzing present condition of water supply in Erhuang District and com bined with the development trends in optimal operation by multistage pumping stations. By using VB 6.0 and MATLAB programming software ,mostly get the following research findings: (1)The model building and applying of pump station interior optimal operation On the basis of definition of the mathematic model of pumping station in dispatching, and considering the min energy consumption of dispatching goal, the author choose dynamic programming to settle the problem. Therefore joins xi - 0, 1 variable, using the binary system shows the set station under each kind of combination condition, finally obtains the smallest energy consumption under all combinations condition, thus finally get the set condition.(2)The model building and applying of multistage pumping station head optimal operation The head optimization of the multistage pumping station system relates and affects mutually with various pumping stations head. By taking various pumping stations lifts as the connection variable, the multistage pumping station mathematical optimal operation model is established.(3) The development of Erhuang multistage Pumping Stations management information system based on VB6.0 visualization language and MATLAB software.The operation of multistage Pumping Stations water supply project is to be automated, visual, and with informatization, the becoming an information based society direction has developed, Erhuang project also urgently need the change the present situation that operate artificially depending on experience.Therefore, this article has developed Erhuang multistage water supplies optimal operation management information system by taking VB6.0 as the platform together with MATLAB software.This system has provided data inquiry, water management as well as optimal operation,and so on. This can provides technical support for Erhuang water supplies project project operation.
