Embodiment Construction

[0023] The present invention will be further described below in conjunction with accompanying drawing:

[0024] Such as figure 1 As shown, the method of the present invention comprises the following specific steps:

[0025] Step 1. Comprehensively analyze the technical and economic factors affecting the zoning, and determine the reasonable number of zoning: according to the specific situation of the example pipe network, set the number of zoning to 12;

[0026] Step 2, spectral clustering optimization: for figure 2 For the hydraulic simulation of the water inlet of the example pipe network, an undirected graph is established with the pipe flow as the weight, and the most reasonable number of partitions is determined with the modularity as the index, such as image 3 As shown, the reasonable number of eigenvectors is 6;

[0027] Step 3, determine the partition boundary: According to the node clustering, find out the connecting pipes between different clusters, that is, the ...

Abstract

The invention discloses a method for optimizing the positions of water meters and valves in water supply network zones. A spectral clustering effect is improved by determining the reasonable feature vector number based on a spectral clustering minimized-cut theory in graphic partitioning, and boundary pipelines in the zones are determined; then, by analyzing the importance of nodes and the pipelines, a shortest path and a heuristic algorithm are utilized to determine the positions of the water meters and the valves in the zones on the basis that the connectivity and zone water pressure requirements are considered, and finally zone planning is completed. The method has a great application value due to a perfect theoretical basis and a good application effect and provides a very good reference for the practice and research of the water supply network zones.

Description

technical field [0001] The invention relates to the field of water network installation and management, in particular to a water supply pipe network partition method based on spectrum clustering. Background technique [0002] The water supply network partition is to form an independent water supply area by installing water meters and valves under the condition of minimal impact on system performance, which is convenient for optimal scheduling, leakage control and other aspects of management to meet the requirements of informatization, intelligence, and refinement. There are many technical requirements that need to be considered in the division of the pipe network, and the reasonableness of the water meter and valve position directly affects the performance of the division of the water supply pipe network. At present, some zoning methods only preliminarily determine the zoning boundaries, but lack methods for optimally determining the positions of water meters and valves in t...
