Power equipment name identification method

Abstract

The invention discloses an electrical equipment name identification method. The method comprises the following steps: (1) constructing a power grid professional lexicon for storing vocabularies; The method comprises the following steps: directly adding a single vocabulary, directly adding more than two vocabularies, and screening and adding vocabularies; (2) realizing word segmentation: generatinga triplet search tree from the professional lexicon, and combining the digital search tree with the binary search tree to realize quick word segmentation; obtaining a character string array or a character string list; (3) dividing the name of the equipment to be identified and the name of the standard equipment into a character string array or a character string list according to the step (2), and extracting characteristic words which possibly conform to a place to which the equipment belongs and a voltage level; (4) screening a standard equipment name database according to the feature words;carrying out similarity calculation on two character string arrays obtained after word segmentation is carried out on the name of the to-be-identified equipment and the name of the standard equipment, and acquiring similarity value between 0-1; for the similarity value between 1 and 2, judging the character string meeting the condition by setting a threshold value, and selecting a corresponding data entry; And equipment recognition degree identification is realized.

Description

technical field [0001] The invention relates to the field of electric equipment name identification, in particular to an electric equipment name identification method, which can accurately identify the name of the electric equipment and improve the accuracy rate of electric equipment name matching. Background technique [0002] Due to the lack of unified and standardized management of power grid equipment naming standards, the current dispatching system applications often have and maintain one or more sets of ledger information, which leads to the involved equipment ledger information and D5000, OMS equipment in each network province There are a lot of inconsistencies in the naming in the ledger, which reduces the compatibility and scalability of the application. In the prototype of the developed device matching tool, the LD similarity algorithm and the jarccard similarity algorithm are used to match the similarity of the data in the specified column in the configuration dat...

[0002] Due to the lack of unified and standardized management of power grid equipment naming standards, the current dispatching system applications often have and maintain one or more sets of ledger information, which leads to the involved equipment ledger information and D5000, OMS equipment in each network province There are a lot of inconsistencies in the naming in the ledger, which reduces the compatibility and scalability of the application

In the prototype of the developed device matching tool, the LD similarity algorithm and the jarccard similarity algorithm are used to match the similarity of the data in the specified column in the configuration database, and output a comparison table for entries greater than the set threshold to solve most common naming mismatches. However, its accuracy rate is not high, and it is difficult to meet the needs of users, so it is necessary to propose a matching algorithm with higher accuracy (matching items: the matching of the maintenance equipment in the maintenance ticket and the D5000 naming and dispatching naming in the line, switch, and bus table requires matching Other dimension items in the line, switch, and busbar tables can be associated and matched, such as the voltage level and switch number columns in the switch table)
