The invention provides a power grid distribution image drawing method. The method comprises the following steps: collecting a remote sensing geographic image of a to-be-drawn area, wherein the remote sensing geographic image is an image with sub-meter resolution; acquiring geographic coordinate data of marker nodes in a system database, the marker nodes are a power station, a transformer substation and a tower pole; screening the marker nodes in the remote sensing geographic image according to the obtained geographic coordinate data, and marking the screened marker nodes; and according to a power grid topological structure, drawing connecting lines among the main network equipment nodes, the power distribution network equipment nodes and the marker nodes for the marked remote sensing geographic image to form a power grid distribution image. In the technical scheme provided by the invention, the geographic remote sensing image is used as a basis for drawing the power grid distribution diagram, the association between the power grid distribution and the natural environment can be accurately reflected, and the power grid drawing efficiency and accuracy are ensured.
Description
technical field [0001] The present application relates to the field of power grid drawing, in particular to a grid distribution image drawing method. Background technique [0002] Drawing the distribution map of the power grid is an effective means to supervise and detect the distribution of the power grid. The distribution network structure includes main nodes such as power stations, substations, and transmission lines. Generally, the connection relationship between nodes needs to be drawn clearly in the distribution diagram of the power grid. [0003] The traditional power grid distribution map drawing method mainly imports the known geographical coordinate information of the above nodes directly into the power grid system to form a vector map of the geographical correlation of each node in the power grid, and obtain the final power grid distribution map. [0004] However, in the actual application process, the power grid distribution map drawn by the above method has the...
