Research Of Partition Optimization Based On The Hydraulic Model Of H City

Water supply network is an important link in the urban water supply system.If it can meet the demand of users available water safely and reliably will directly affect People's Daily life and social production.It is also important to energy consumption of the water supply system,it has a great energy saving potential.To reduce the energy consumption of the water supply system can not only save energy,also can improve the water supply enterprise economic benefits.Due to the water supply pipeline installation,continuously expanded,water supply system in our country in the aspect of planning and design,operation and management are unreasonable phenomenon.These phenomena cause the network poor safety of water supply,unbalanced pressure thus prone to tube-burst accident,such as the use of electrical energy efficiency is low,wasted energy,increase the cost of the enterprise.In this paper,the study of urban water supply network system,starting from several main aspects of water supply system,for the study of water supply network system optimization partition,solve the imbalance of water supply pipe network pressure,and can't meet the demand of users to the problems such as,at the same time,achieve the goal of economic and energy saving.Along with the social development of science and technology and the gradual improvement of the people demands for water supply system,water supply pipe network layout of scientific and reasonable line gradually are taken seriously.This article is in reference on the basis of predecessors' research results,considering pipe network pressure balance,leak rate,saving energy and reducing consumption,lower cost factors such as the optimization of water supply network system partition were studied,to improve the service quality of the water supply system,promote water supply system plays an important role in its economic benefits and social benefits.This topic main research:Analysis and study of water supply network system partition optimization theory,the establishment of the water supply pipe network hydraulic model and check,with T city actual water supply pipe network hydraulic model based on network partition optimization case study.The first comprehensive analysis of network partition theory.Analysis of the basic concepts,optimization of network partition and research,pointed out in this paper,considering the pipe network pressure balance,hydraulic conditions,leak rate control,saving energy and reducing consumption,lower cost and so on important factors as the basis of network partition optimization.The second is the establishment of the water supply pipe network hydraulic model and checking.In water supply network based dynamic hydraulic modelsimulation theory and method,analysis and research T city pipe network,find a suitable for the application of the network node flow distribution methods,including open water and bad water production and sales.Studing comparing water model method for the establishment of regular curves(water),pointing out that the water model of vertical method is used to get higher accuracy and more consistent with the actual condition of water.To explore the different types of pump running together,Pump actual characteristic curve are obtained.Using Darwin automatic checking to check the model.,Making pressure monitoring error range within the plus or minus 2 m reached 100%,In the plus or minus 1 m can reach 85.72%.Meet the requirements of the model for accuracy.T the city water supply pipe network hydraulic model is established,the research laid the foundation for further optimization of partitions.Finally on the basis of the established water supply pipe network hydraulic model,appling hydraulic model to network optimization analysis and research of the partition,develop urban water supply pipe network partitioning scheme.According to the theory and principles of water supply network partition optimization,considering network partition important influence factors in choosing the optimal solution.Achieve stable pipe network pressure,meet user demand,water saving energy consumption,reduce the enterprise cost of water supply.
