Water supply pipe network affair model modelling approach based on transient flow analysis

Disclosed is a modeling method for water distribution network event driven models, based on transient flow analysis; the method belongs to the water distribution network dynamic simulation field and is characterized in that the method comprises the following hardware: an in-situ industrial object, a status acquisition and control equipment for the industrial object, a communication network, a host machine deployed in the control center, a server database, a client terminal and a large-screen display unit; the method also comprises the following software: a GIS-based water distribution network basic data and time-course data database deployed in the server database, a constant flow calculation model, a water distribution network state estimation and calculation method, a water distribution network event driven analysis model based on transient flow analysis, and a GUI interface deployed in the client terminal. Through the test point water pressure, the flow data and the industrial object state data, the water distribution network state estimation and calculation method is applied to estimate the network state, and the water distribution network event driven analysis model is applied to analyze the network hydraulic transient change process, then the network state real-time change process is displayed at the client terminal or on the large-screen display unit to show the network state change process.
