Description

Technical Field

[0001] This invention relates to the field of water resource regulation technology, specifically to a method and system for structurally representing complex water supply networks. Background Technology

[0002] Currently, water network topology maps used for water resource allocation often directly connect the "water source end" and the "user end," rarely considering the flow of physical water in various stages of the "engineering end," such as water source projects, water purification and distribution projects, and pipeline projects. They almost never involve virtual water analysis of the user end, which leads to insufficient refinement in water resource allocation. Summary of the Invention

This system can generalize the three-level water supply network system of "water source - water conservancy project - regional enterprise" on the supply side, meet the technical requirements of the interactive configuration of water supply, use, consumption, discharge and recycling of physical water resources, and connect with the water consumption of enterprises on the demand side for product production, thus providing support for the overall configuration of physical and virtual water.

[0171] It should be noted that the water supply network structure of coal-based energy and chemical industry bases can be connected and combined in a maximum of 2 ways. [S ×W+J×(W+2RW+PT+DT)+PT×DT] There are several possible combinations, with the largest number of pipelines (i.e., all nodes are connected) being S×W+J×(W+2RW+PT+DT)+PT×DT. Furthermore, the connection between two nodes is not necessarily achieved by only one pipeline. For example, a water treatment plant supplying water to users requires first reaching the distribution point via the outgoing pipeline network, and then delivering the water from the distribution point to various industrial parks or mining areas via the incoming pipeline network, further increasing the system's complexity. For cases where multiple pipelines connect two nodes, there is no need to differentiate them through pipeline generalization; they are simply expressed in the model constraints based on water supply capacity.

[0176] A modular processing module is used to modularize the complex water supply network based on the correspondence to obtain several modules;

[0177] A tag attribute module, which is used to tag the attributes of each module;

[0178] A matrix representation module is used to generate a structured representation of the complex water supply network based on the attributes of each module.

[0180] The node partitioning submodule is used to perform node partitioning operations on the complex network to obtain a number of nodes;

[0181] The channel determination submodule is used to determine several channels in a complex water supply network based on the several nodes.
