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 saves the current branch direction of each ...

Abstract

The invention provides a geographic information based automatic distribution method of power distribution singlet lines in a grid. The method mainly includes: an object generation and update phase, namely generating an initial layout of a singlet line diagram, calculating spatial scale occupied by equipment and branches on the lines by adopting a bottom-up iteration calculation method and providing data support for subsequent space expansion and compression; a space expansion phase, namely moving the affected lines and equipment to enable the spatial positions of the branches and equipment are not overlapped in occupation according to spatial occupancy data of objects and branches stored in the previous phase; a space compression phase, namely reversely performing compression operation on the adjusted space through judgment of heuristic space occupancy and according to adjustment performed in the expansion phase till the spatial positions are minimized in the allowable range. Through the support of the automatic distribution method, practical initial layout of the power distribution singlet lines and incremental layout adjustment support are provided, and practical need of the power distribution singlet line diagram function is met.

Description

technical field [0001] The invention belongs to the field of power grid geographic information systems, and in particular relates to an automatic distribution method for power distribution single lines 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 in ...
