Optimal arrangement method for flow monitoring points of urban water supply pipe network

Abstract

The invention discloses an optimal arrangement method for urban water supply pipe network flow monitoring points. The method comprises the following steps that a water supply pipe network hydraulic model is constructed; a water supply pipe network flow monitoring point optimal arrangement model is constructed, constraint conditions of the model are a pipe network node flow continuity equation, a pipe network node water pressure constraint condition and a pipe network energy conservation equation, and a sensitivity equation of pipe network node flow to pipe network node pressure is established;Pearson correlation analysis on the sensitivity equation is adopted in the optimized arrangement model for calculating the flow monitoring points of the water supply pipe network, a simple normalization equation is solved, the arrangement positions of the pressure monitoring points and strong correlation points of the pressure monitoring points are solved, and an optimal flow monitoring point scheme is determined. According to the method, the arranged pressure monitoring points can well reflect the change condition of the node pressure, the reliability of the monitoring points is improved, meanwhile, the node range capable of being monitored by each pressure monitoring device can be determined, the requirements for representativeness, comparability and feasibility of point distribution are met, and blindness of selection of the pressure monitoring points at present is reduced.

Description

technical field [0001] The invention belongs to the field of arrangement of flow monitoring points of a municipal water supply pipe network, and relates to a method for optimizing the arrangement of flow monitoring points of a water supply pipe network. Background technique [0002] Urban municipal pipe network is one of the most important infrastructures of modern cities and an important symbol of urban civilization, development and modernization level. The water supply network is not only the lifeline of the city, but also an important guarantee for improving the quality of life of citizens and the ecological environment of the city. [0003] In order to effectively monitor the municipal water supply network, it is necessary to set up pressure monitoring points for flow data collection. This not only intuitively understands the flow distribution of the entire water supply network, but also has practical significance for controlling water supply network leakage and pipe bur...
