Abstract

The invention discloses a power grid edge layout mapping method and device based on geographic information. The method comprises the following steps: determining the starting position of a power grid starting node for any power grid starting node in a power grid geographic information graph; according to the power grid starting node, determining any power distribution line taking the power grid starting node as a starting point and a power grid termination node of the power distribution line, and according to the power distribution line, determining a final position of the power grid termination node; according to the starting point position and the final point position, determining a shortest path between the starting point position and the final point position according to an A star path planning algorithm; and generating a power grid edge layout of the distribution line according to the shortest path. Therefore, the method can achieve the automatic generation of the power grid edge layout based on the geographic information, and improves the generation efficiency and accuracy of the edge layout.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a method and device for forming a grid layout along the grid based on geographic information. Background technique [0002] With the continuous construction of smart grid and distribution network system, the maintenance cost of power grid graphics continues to increase. The grid distribution network along the layout has become an important platform and means to show the operation status of the distribution network, and it is also a must for maintenance and infrastructure departments to carry out work Indispensable information. [0003] In practical applications, the distribution network of the power grid is distributed along the Figure 1 Generally, business personnel use drawing tools or special drawing software for power systems to draw manually. This drawing method relies heavily on manual input and maintenance, and the drawing efficiency is low and the drawing accuracy is...
