Optimization Research Of Rural Water Supply Network Based On Adaptive Genetic Algorithm

In the modernization process of countryside,the construction of water supply system is very important.As a part of the infrastructure,it has an important influence for the long-term development of the countryside.However,the construction of rural water supply system in our country is huge,in which the energy consumption of the pipe network construction is quite high.It even can reach the 60% to 80% of the total investment.Investigates its reason,this is not separated from the reality of our country’s rural areas.China’s rural residents live in certain dispersion and need a larger area of water supply.The pipeline of water supply generally adopted the mixed pipe network or tree pipe network.And the arrangement is very intricate.In addition,the weak rural economy and the insufficient foundation construction bring the difficulty to the construction of the rural water supply system.Therefore,the author based on the study of domestic and foreign literatures and combined with the actual situation of the construction of rural water supply system in our country.Finally,explored a set of suitable network planning for China rural water supply.Meanwhile,the author putted forward an optimal scheme and the most reasonable calculation method for the construction of the rural water supply system.The specific contents of this paper are as follows: On the basis of absorbing the previous research results,the system model of rural water supply network is constructed with the constraint conditions of water supply reliability and the economic performance as the objective function.In the objective function,the core is obtained the economic pipe diameter.This function takes the pipe flow rate,the flow rate and the free water pressure as the constraint conditions,and strives to achieve the lowest cost of the water supply pipe network and the lowest operating cost.At the same time,the Excel table is used to calculate the head loss and flow rate of the pipe section.In the paper also checked and ensured the economic pipe diameter can not be eliminated because of hydraulic constraints.Finally,the feasible solution space is enriched.In order to verify the scientific nature of the target model,this paper will be applied to the practical application of water supply project in the Qian Sun Village of Yanshan County.MATLAB is used to calculated the program.The following conclusions are drawn: this article adopted the adaptive genetic algorithm,which proved more economical than the traditional excel form optimization algorithm.This method also can achieve the optimization of pipe network design.In summary,this paper aims to provide a more reasonable and scientific method for the construction of rural water supply system.Trying to save construction costs and maintenance costs,in order to obtain higher social returns at a lower economic cost.This paper studies from the actual demand of China’s rural areas and has its theoretical significance and practical significance.Hoping the research results of this paper can provide reference for the construction of water supply system in rural areas.
