Abstract

The invention discloses a retrieval method and device for power grid dispatching structural data. The method comprises the steps that inquiring words input by a user are received; a semantic expression corresponding to the inquiring words is inquired in a pre-structured semantic expression template in a matched mode; the semantic expression is analyzed, and an inquiring expression is obtained with the combination of the inquiring words; retrieval is carried out in a pre-structured structural data retrieval file according to inquiring conditions in the inquiring expression, and retrieval results are obtained, wherein the structural data retrieval file is established based on the relation between structural data and a pre-structured power grid dispatching field knowledge base which includes key words, types to which the key words belong, and relations between one or more characteristics corresponding to the types or between the types, and the retrieval results include data associated with the inquiring words; the retrieval results are ranked according to preset ranking indexes; ranked retrieval results are output. According to the retrieval method and device for power grid dispatching structural data, the retrieval results are accurate, the retrieval efficiency is high, and associated data can be provided for the user.

Description

technical field [0001] The invention relates to the technical field of power grid dispatching automation, in particular to a retrieval method and device for power grid dispatching structured data. Background technique [0002] With the continuous development of the power industry, the daily management information processed by power grid organizations is increasing rapidly. On the one hand, due to the increasingly complex structure of the power grid, both the number and type of connected devices have increased significantly; on the other hand, because the quality standards of power supply have been continuously improved, the timeliness of the grid organization's processing of various production information and management information has been required to be enhanced. [0003] In the field of power dispatching control, with the gradual deepening of the construction of the two-level distributed dispatching management system in northern Hebei Province, the degree of informatizati...
