Abstract

The invention provides an automatic mapping method for a distribution network based on logical layout. The method includes: (1) pretreating a model of the distribution network model by analyzing it, and partitioning and striping the distribution network model to generate a plurality of partial models; (2) analyzing an automatic mapping algorithm to be utilized by comparing a distribution network graph obtained by the algorithm with the distribution network model; (3) achieving automatic layout of the partial models or the whole distribution network model on the basis of analysis of the automatic mapping algorithm to be utilized; and (4) analyzing and treating the automatic layout to achieve the generation of the distribution network graph with a desired practical effect.
