Knowledge graph-based power grid knowledge sharing and intelligent decision technology service method

Abstract

The invention discloses a power grid knowledge sharing and intelligent decision technology service method based on a knowledge graph. The method comprises the following steps: constructing intelligent decision assistance; construction of power grid knowledge sharing and construction of a knowledge graph. According to the power grid knowledge sharing and intelligent decision technology service method based on the knowledge graph, retrieval, reuse, modification, adjustment and reservation of a case library are carried out through intelligent aid decision making, an integrated mode of case reasoning and rule reasoning is adopted and is divided into three integrated modes, case reasoning is carried out in a limited mode during retrieval, and the efficiency of case reasoning is improved. If a retrieval result is not ideal and an emergency target still exists, an integration mode is started, a required decision scheme is deduced from a database, continuous updating learning of new cases and historical cases can be realized through the mode, meanwhile, the stability of new case retrieval is guaranteed, and the efficiency of new case retrieval is improved. And omission and errors are prevented when the historical cases are filtered and retrieved.

Description

technical field [0001] The invention relates to the technical field of grid knowledge data construction, in particular to a technical service method for grid knowledge sharing and intelligent decision-making based on a knowledge graph. Background technique [0002] With the rapid development of State Grid Corporation of China, the continuous deepening of power informatization and the continuous expansion of power application fields, power data is growing at an unprecedented rate. The digital revolution is not only the trend of the current era, but also the key to the company's strategic goals. The value of data resources, improving the level of information integration of power grid dispatching, improving the level of standardized management of power grids, and exploring new models for cultivating digital economy are the company's priorities. [0003] However, the current low level of standardization cannot meet the needs of overall regulation and management. The power grid ...

Problems solved by technology

[0008] The purpose of the present invention is to provide a service method based on knowledge graph grid knowledge sharing and intelligent decision-making technology to solve the current low standardization level that cannot meet the needs of regulation and overall management; the data itself is not highly structured and difficult to automatically Correlating defects, procedures, plans, real-time data and equipment attribute data requires artificially querying relevant information from different systems; the level of intelligence is not high, and it is difficult to achieve daily extraction and in-depth analysis in the face of historical power grid information data, which is not conducive to Instruct the person in charge of relevant data to predict, analyze and summarize relevant data
