Method for implementing intelligent layering of wiring diagram of distribution area

The invention discloses a method for implementing intelligent layering of a wiring diagram of a distribution area. The method includes the following steps that graphic elements and practical line setting elements are divided into foundation elements, dependence elements, connection elements and other elements, and the elements correspond to equipment information; in the wiring diagram of the distribution area, a connection sequence is established by taking a distribution transformer as a head node and taking user loads as end nodes, a classification model is established in a line outgoing mode, and a topological relation is established; with the combination of a topological structure, virtualization processing is conducted on the nodes, and the nodes are sorted; extraction, combination, virtualization and intelligent layering of elements in a layer tree structure are achieved by establishing a topological structure and nodes in a current network architecture, and a partition a topological structure is established. A part of lines in the distribution area of a power supply area can be selected rapidly, the frequency of selection of head nodes and end nodes is reduced in the production process, practical service operations such as load prediction and power supply capacity assessment are carried out, and a basic support is provided for analysis of distribution area building.
