| The model for water supply pipe network is the most effective way of simulatingwater distribution network dynamic conditions, which can provide the most valuableinformation of water supply system and help to water supply network managersrealize scientific and modern management. With we out setting up water distributionnetwork system model, a high quality water pipe network model can optimize thepipeline network system, control Leakage of water and guide pipe network systemoptimization operation, which is the development direction of scientific andtechnological innovation at urban water supply in our country, and is the recent urgentproblem in the water industry.To realize optimal operation of the south-to-north transfer water and local Beijingwater, ensure the safety and stability of the capital water supply, we must set up thecircle delivery pipe hydraulic model for Beijing South to North Water TransferProject, and master the real-time running situation of the network, set up reasonableoffline and online operation planning and scheduling solution, schedule the pump ofeach pump station consistently, keep optimization distribution of water amount andwater pressure in the pipeline network system, optimize water supply energyconsumption and cost optimization water supply, reduce probability of the networkpipe explosion accidents, and improve the safety of water supply.Pipe network system data is the foundation of network model, the managementand maintenance to network data is one of the key technology of keeping waterdistribution network model operation efficiently, The author analysed modeling datatypes and demand,and put forward the comprehensive evaluation method that canjudge the data is accurate or not.This article introduces the process of building up the delivery pipe model forBeijing South to North Water Transfer Project based on Info Works WS software,including the contents which are introduction of project basic information, buildingthe network, ensuring the pipe friction coefficient, founding and checking the model,and maintaining the model.Introduce and analyse the six working conditions of circle delivery pipe, simulatethe typical working conditions operation by the model, analyze and compare betweenthe data from the model operation and the data from design, and find the model cansimulate real-time state on pipeline network very well, and make a scheduling plan;meanwhile it has an effect of guiding and aiding decision making for the currentproject. |
