Reliability Analysis Of Water Distribution System Based On Experimental Platform With Different Conditions

With the expansion of the scale of urban construction, the size of the waterdistribution network is growing, its structure is getting more complicated, it alsohighlights an important position in the urban infrastructure out.For waterdistribution network’s design, operation, management and maintenance,the waterdistribution network hydraulic model is the maximum utilization method.For now,we have in the system design, operation, management and maintenance of the watersupply network, the maximum utilization of the method is created for the hydraulicmodel of the water distribution network.Therefore, in-depth study to the waterdistribution network model calibration and reliability analysis of water distributionnetwork is a theoretical significance and practical value. This article is mainlythrough the National Water experimental center in northern water supply pipenetwork experiment platform based on reliability analysis using differenttopologies in different conditions.IT based on the the Hazen Williams coefficient ofpipe resistance coefficient.The pipe network in accordance with the different valveopening, different topologies (valve switch to change the pipe network topology) toform different working conditions, pressure sensors collect data from devices in thefield, and to use these data to draw water pump characteristic curve, calculatedwater supplythe sensitivity of the Pipe, and EPANET software created for the waterdistribution network model.Obtained multi-condition variable metric geneticalgorithm gradation correcting both global and local search capability, highefficiency and correction accuracy. Pipeline valve opening adjustment and districtwater supply affects the reliability of the entire water supply pipe network. InEPANET not only has the general hydraulic calculation software pipe networkadjustment calculation function, can simulate Water supply network.
