A power grid geographical wiring diagram automatic generation method and device

Abstract

The invention discloses a power grid geographical wiring diagram automatic generation method and device, and the method comprises the steps of carrying out the initial layout and local offset of all A-class along distribution units and B-class along distribution units, and obtaining all node equipment layout diagrams of the A-class along distribution units and the B-class along distribution units under a rectangular coordinate system; for the layout of the line equipment in all the A-type along cloth units and the B-type along cloth units under the rectangular coordinate system, obtaining all line equipment layout diagrams; combining the line equipment layout diagram with the node equipment layout diagram to form a power grid layout diagram; converting rectangular coordinates of the node devices and the line devices in the power grid layout diagram into geographic coordinates through Mercator projection, marking the node devices and the line devices on a geographic map according to the converted geographic coordinates, and finishing automatic generation of the power grid geographic wiring diagram. According to the a power grid geographical wiring diagram automatic generation method and device, the mapping efficiency and the equipment identification degree in the diagram are remarkably improved, and the method and device can be used for businesses such as power grid equipment management, operation and maintenance and the like.

Description

technical field [0001] The invention relates to a method and device for automatically generating a geographic wiring diagram of a power grid, and belongs to the technical field of power grid equipment management and operation and maintenance information technology. Background technique [0002] Geographic wiring diagram is a basic graphic commonly used in distribution network operation and maintenance management. It has a wide range of application scenarios in the visualization of power outage information, auxiliary formulation of business expansion and installation plans, emergency repairs, and life cycle management of power assets. [0003] At present, the relevant research on the automatic generation technology of the grid geographic wiring diagram is very limited. The maintenance of the grid geographic wiring diagram of the State Grid Corporation of China is still based on manual drawing. This method is slow in efficiency and the drawing accuracy is uncontrollable. The e...

[0003] At present, the relevant research on the automatic generation technology of the grid geographic wiring diagram is very limited. The maintenance of the grid geographic wiring diagram of the State Grid Corporation of China is still based on manual drawing. This method is slow in efficiency and the drawing accuracy is uncontrollable.

The existing drawing method does not consider how to arrange the equipment on the pole (such as the switch on the pole, the transformer on the pole, etc.), because the plane space position of the equipment on the pole is the same as that of the tower, if the layout is not reasonable, it will cause The equipment on the column overlaps with the tower on the diagram and cannot display the topological connection information of the equipment on the column
