Water supply pipe network real-time scheduling system and method

Abstract

The invention discloses a water supply pipe network real-time scheduling method, which is characterized by, to begin with, predicting minute-level water demand by utilizing real-time water volume data; then, pre-estimating pipe network operating state by utilizing real-time model simulation; and then, determining scheduling decision in the next time section through optimization search. The system, on the basis of an EPANET-RTX water supply pipe network real-time model, guides the scheduling decision by fully utilizing real-time data collected by the water supply pipe network basic automation and information system, and through short-term water demand forecasting and operation state estimation and the like on the basis of accurately reflecting the state of a water supply pipe network; and compared with a common scheduling method, the method is better.

Description

technical field [0001] The invention belongs to the field of urban water supply, in particular to a real-time dispatching system and method for a water supply pipe network. Background technique [0002] With the rapid development of urbanization and industrialization in our country, the scale of urban water supply pipe network system is gradually increasing, and the topological structure tends to be complex. As a result, the current dispatcher's command and dispatch method based on personal experience is increasingly unable to meet the requirements of real-time dispatch. [0003] At present, most domestic explorations of solutions to real-time scheduling problems of water supply networks are based on macro-hydraulic models. Since the macro-hydraulic model is driven by data, the scheduling scheme based on this must have defects, such as the inability to obtain the operating status of non-measuring points, and when the topology of the pipeline network changes due to reconstru...

AI Technical Summary

Problems solved by technology

Since the macro-hydraulic model is driven by data, the scheduling scheme based on this must have defects, such as the inability to obtain the operating status of non-measuring points, and when the topology of the pipeline network changes due to reconstruction, expansion, maintenance, etc., the original scheduling Method can fail due to model inaccuracy

The invention patent is to directly use real-time water volume data to carry out water supply scheduling. Although it can improve the response speed to a certain extent, due to the lack of support from the real-time model of the water supply network, it is impossible to fully understand the real-time status of the water supply network, which will inevitably affect the dispatching decision-making effect.
