Embodiment approach

[0049] The present invention provides a method for constructing a unified distribution network grid topology based on graph fusion technology, which includes the following steps:

[0050] The first step: collect the metadata of the account data in the three business systems of marketing system, production management system (PMS) and geographic information system (GIS); according to the marketing system, production management system (PMS), geographic information system (GIS) ) the metadata of the ledger data in the three business systems, sorting out the differences in the ledger data among the three business systems. Eliminate obsolete data, invalid data, and duplicate data in metadata, and retain valid data.

[0051] What the marketing system lacks are: main line, electrical equipment container (ring network cabinet, switching station, cable branch box, box-type substation), conductive equipment (conductor, circuit breaker, isolating switch, load switch, distribution line sec...

Abstract

The invention discloses a unified distribution network frame topology construction method based on a graph fusion technology. The unified distribution network frame topology construction method comprises the following steps: step 1, data processing: collecting metadata of ledger data in three business systems including a marketing system, a production management system and a geographic informationsystem; preprocessing and reserving effective data; step 2, constructing a power distribution network frame meta-model; step 3, constructing a single-system grid structure topology: storing the constructed power distribution network grid structure topological graph in a graph database; and step 4, constructing a fused power distribution network frame topology: constructing a unified power distribution network frame topology by utilizing a graph fusion algorithm and combining the constructed single-system network frame topology. According to the invention, transverse consistency comparison check and longitudinal data accuracy check of machine account data of different systems can be realized, and self-service data check and governance services are provided for the system; and according toa governance result fed back by a business department, iteratively improving data governance and identifying model accuracy and efficiency.

Description

technical field [0001] The invention belongs to the technical field of electric power information, and in particular relates to a method for constructing a topology of a unified distribution network grid based on graph fusion technology. Background technique [0002] At present, in power grid companies, distribution network ledger data is stored in the marketing system, production management system (PMS), and geographic information system (GIS), and the attribute dimensions of these system ledgers stored in each system are different. Some systems It has some equipment ledgers that are duplicated with other systems, and some equipment ledgers that are unique to its own system. [0003] The ledger data quality of these distribution network systems is not high, mainly manifested in the wrong ledger data relationship in the marketing system, production management system (PMS), and geographic information system (GIS), inconsistent ledger data attributes, inconsistent measurement ...
