Description

technical field [0001] The invention relates to the technical field of urban water supply management, and more specifically, to a method and system for real-time verification of 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 pipeline systems. For example, a water utility can use a water supply network model to help select the appropriate pipe diameter, analyze the hydraulics and water quality safety at the end of the network, calculate the energy consumption of water pumps, and more. [0003] At present, the water supply network models are 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 relatively easily obtained offline. The operating parameters of the pipeline network system, such as the working conditions of pumps and valve...
