Study On The Operational Design And Optimization Atemper Of The Water Distribution Network In The City

With the fast development of our country economy, the urban population increases continuously, the industry produces the ability to improve increasingly, the request of the city water supply system will be more and more higher, and the scale will be increasingly huge. The complexity of the water supply system also will be increased and the traditional experiential attemper can not fit for the demand of the nowadays society's development, the optimal attemper and manger of the water supply system will become more important.This paper is to take the pipe network of HanDan City as an example, carrying on the analysis and research to the movement condition of the water supply system of HanDan City, according to the mathematics model, the algorithms, the modern control theories and the Forecasting; combine to the model of the optimal attemper, optimize the design of the water supply system. At the same time, in order to improve the credibility and the economy of supply water the system, we apply the computer technique to the emulation of the water supply system and empolder the software of the optimal water supply system by pipe equation, mathematics model, and so on.The optimal attemper of the water supply system is by the fullinquisition research to the water supply system, find out the currently existent problem of the pipe network in the construction and circulate, manage. Definite the means of the modeling data aequision, is a quality control that takes care of the pipe network to set up the model. On this foundation, the optimal model of the water network is set up, combine the imitated calculation with the artificial experiences analysis availably, put forward match practically, easy to carry out, economize the energy, economical funds of water supply system.The main contents of the study include analysis of the HanDan City 's water supply system and research the modes, the optimal disposition of the manometric point, the disposal of the mathematical digital, simulation of the practical state; and set up the model of the optimal attemper and open out the software of the optimization of pipe network; Reflect with the form of the friendly interface the model and data to the governor at the same time, for adjust one degree decision service; Make use of the computer interface control technique to attain the optimal control of the system, finally carry out the whole system to turn to optimal attemper.The software that developed by the study completes the hydraulic analysis to the water pipe network of HanDan City, make use of the result of the hydraulic calculation draw the water supply boundary of the two water factories in the HanDan City and the most disadvantageous section of the pipe network in the HanDan City; combined the water supply system in each factor of movement condition do an adjustment and put forward improve suggestion with the problem of the pipe network, then while satisfy the premise of supply water the water quantity, hydraulic pressure,save the energy, optimal attemper.The software of the optimization of the HanDan City's water supply system has a lot of merits, as follows, adjust to the water quantity change the adaptability strong, input the basic data little, to the problem have little request, maneuverability strong, easy to maintenance etc. Using this software, adjust the plan of water supply in HanDan City, basically come to the anticipant purpose. The software not only be applicable to the city water supply pipe network of the HanDan City, but also can apply to the other cities in the analytical calculation, provide strong support for the pipe network rebuild, the more important, while satisfy the premise of the water quantity, hydraulic pressure request, with maximum limit raise the economic benefits and social benefits of the water supply systems, improve the credibility, safety and economy of the water supply system, have very vast applied foreground.
