Problems solved by technology

Due to differences in technical level, work experience, and operating habits among different technicians, it is difficult to unify the one-line diagrams drawn, and the quality varies, making it difficult to achieve unified and standardized management
At the same time, due to frequent changes in the power distribution network, it is difficult to ensure that the one-line diagram can be updated in a timely and accurate manner in the traditional way, which brings inconvenience to related management work

Embodiment Construction

[0030] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0031] First refer to figure 1 It is the overall processing flow chart of the embodiment of the present invention. Before explaining the processing steps, first define the concepts related to the topology and layout of the one-line diagram, and describe the corresponding data structures. in:

[0032] Definition 1: Equipment node, each base tower and pole-mounted equipment (switches, switches, drops, transformers, etc.) It is treated as an independent device node. In the case of expanding the internal wiring of station equipment, all expanded objects are treated as a device node as a whole.

[0033] Definition 2: Node offset value, the node offset value data structure stores the current branch direction of each...

Abstract

The invention provides an automatic layout method of a distribution single line diagram in a grid geographic information system, which mainly comprises the following steps of: an object generating and updating stage: the initial layout of the single line diagram is generated, and space ranges needing to be occupied by each equipment and each branch on a line are calculated by adopting a bottom-up iterative calculation method so as to provide a data support for follow-up space expansion and compression; a space expansion stage: according to the stored object and branch space occupied data in the previous stage, the affected line and equipment are moved, so that the occupied space positions of each branch and equipment are not overlapped; and a space compression stage: according to the adjustment work of the expansion stage, through the heuristic space position occupying judgment, the adjusted space is reversely compressed until the space position is minimized in an allowed range. Through the support of the automatic layout method, the practical initial layout of the distribution single line diagram and the incremental layout adjustment support are provided, and the practical needs of distribution single line diagram functions are met.

Description

technical field [0001] The invention belongs to the field of power grid geographic information systems, and in particular relates to an automatic layout method for power distribution single-line diagrams in the power grid geographic information system. Background technique [0002] Power grid geographic information system (grid GIS system) is a professional information system that uses geographic information (GIS) technology to manage power transmission, power transformation, power distribution and low-voltage power grids. It is mainly used in provinces, prefectures, and counties under the State Grid and China Southern Power Grid. Power supply bureaus, power bureaus or power companies at all levels realize business functions such as graphics management, file maintenance, automatic graphing and topology analysis of transmission, transformation, distribution, and low-voltage power grids. [0003] The power distribution one-line diagram is one of the most important basic data i...
