Problems solved by technology

[0002] The power grid planning in the power system generally follows the empirical processing method, using the land use properties of different areas (such as industrial land, green land, etc.) formulated by the urban development plan to define the power load rate of different areas, and then integrate the power consumption in a certain area. Electric load, if it meets the needs of building substations, choose a reasonable location to build the substation. The previous analysis process basically relied on manual analysis and experience, which was difficult to be accurate and fast, resulting in large deviations in the analysis results. How to analyze quickly and accurately has always been a problem. a difficult problem

Embodiment Construction

[0043] Below in conjunction with accompanying drawing, the present invention is further described:

[0044] The area development map mentioned in the description (such as figure 2 ) is to divide the area into different sub-areas according to different land use properties, which are marked in different colors and accompanied by corresponding legends in the figure.

[0045] see figure 2 As shown, the method for obtaining power grid planning data according to the regional development planning map of the present invention includes the following steps:

[0046] The first step, preprocessing process: regional development planning map (such as figure 2 shown) is divided into three parts in the vertical direction, that is, title, main body area and legend from top to bottom. There will be two wide blank areas in the middle of these three parts. According to these two white areas, the planning map will be divided first.

[0047] Let the original image (color) of the regional dev...

Abstract

The invention discloses a method for acquiring power network planning data according to a regional development planning map. The method includes the steps that the regional development planning map is segmented; all legend information in a legend region is acquired; same regions in the main region of the planning map are separated to form independent subgraphs; all the subgraphs are processed in a binarization mode; the edges of the binary images are extracted; .dxf files corresponding to all the subgraphs are acquired according to the edge extraction result; all the .dxf files are shifted into AntoCAD to form graphs of all the subgraphs in different CAD layers; the power network planning data of the region are acquired according to the region area in each layer of the CAD graph and the planning land usage represented by the layer. According to the method, the development planning sketch map is directly converted into CAD graphs in different layers according to the planned industry with a picture processing method. The method is favorable for making the power network planning result more reliable and acquired faster and more conveniently when a power network plan design is performed according to electricity utilization properties and regions.
