Method and system for real-time verification of water consumption in water supply network model

Abstract

The present invention provides a method and system for real-time verification of water consumption in a water supply pipe network model. A preset state space model is used to obtain the water consumption corresponding to all water consumption nodes at the current moment according to the water consumption estimation vector corresponding to all water consumption nodes at the previous moment. Water consumption prediction vector, using the water supply network model to obtain the water flow prediction vector and water pressure prediction vector corresponding to the current moment according to the water consumption prediction vector corresponding to the current moment; then combine the water flow measurement data and water pressure measurement of all preset monitoring points The data corrects the water consumption prediction vector corresponding to the current moment, and obtains the water consumption estimation vector corresponding to all water consumption nodes at the current moment. The method and system can correct the predicted water consumption according to the monitoring data, so that the optimal estimated water consumption of all water consumption nodes can be obtained in real time, which is beneficial to adjust the water consumption parameters in the water supply network model in real time, and can effectively meet the requirements of the water supply network. Real-time application of models in operations.

Description

technical field [0001] The invention relates to the technical field of urban water supply management, and more particularly, to a real-time verification method and system for water consumption in a water supply pipe network model. Background technique [0002] Computer models have been widely used in the design and analysis of urban water piping systems. For example, a water utility can use a water distribution network model to help pick the right pipe diameter, analyze the hydraulics and water quality safety at the end of the network, calculate the energy consumption of pumps, and more. [0003] At present, the water supply network model is basically used for offline planning, design and analysis. Many model parameters in the water supply network, such as pipe length, pipe diameter, friction coefficient, etc., can be obtained off-line relatively easily. The operating parameters of the pipe network system, such as the working conditions of pumps and valves and the boundary...
