Abstract

The invention discloses an automatic drawing method of a power distribution network diagram based on three-dimensional visualization, and the method comprises the steps: obtaining power distribution node information according to an original topology network of the power distribution network, and determining a hierarchical structure relation between a target power distribution region and the power distribution network; according to the urban information model and the geographic information system, obtaining a three-dimensional model diagram and geographic environment information of the target power distribution area, and determining an overhead line area, a cable line area and power distribution line information in the target power distribution area in combination with a power distribution line construction specification; and performing automatic drawing in the three-dimensional model diagram corresponding to the target power distribution area according to the hierarchical structure relationship of the power distribution network and the power distribution line information to obtain a three-dimensional power distribution line diagram. According to the three-dimensional distribution line diagram, the preparation workload of engineers in the earlier stage of drawing can be reduced, and reference suggestions are provided for the engineers to draw a new distribution network diagram; real and reliable functional environment information is provided for line inspection and equipment maintenance personnel, and the working efficiency and the working quality are improved.

Description

technical field [0001] The invention relates to the technical field of distribution network, in particular to an automatic drawing method of a distribution network diagram based on three-dimensional visualization. Background technique [0002] With the rapid development of the city's industry and real estate industry, the demand for electricity continues to rise, the scale of the power system continues to expand, and the line planning diagram of the distribution network is becoming more and more complex. At present, distribution network diagrams are mostly drawn manually with the help of drawing software. When the distribution network load increases, the distribution network should also appropriately add substations and increase distribution lines to expand the capacity of the distribution network. However, engineering personnel need to do a lot of preparatory work to draw a qualified new distribution network diagram, such as investigating the actual environmental condition...
