摘 要：電網(wǎng)企業(yè)多年技術(shù)監(jiān)督工作開展積累了大量數(shù)據(jù)。針對海量技術(shù)監(jiān)督數(shù)據(jù)挖掘深度淺、數(shù)據(jù)價值低的現(xiàn)狀，提出一種多源數(shù)據(jù)融合的方法構(gòu)建電網(wǎng)技術(shù)監(jiān)督知識圖譜，對其本體設(shè)計、數(shù)據(jù)的獲取與抽取、知識融合及可視化展示等內(nèi)容進行了研究，電網(wǎng)設(shè)備技術(shù)監(jiān)督知識圖譜的應(yīng)用，實現(xiàn)了基于技術(shù)監(jiān)督知識圖譜的智能檢索問答和設(shè)備家族缺陷識別，為電網(wǎng)設(shè)備數(shù)字化管理提升提供了思路。
關(guān)鍵詞：多源數(shù)據(jù)；電網(wǎng)設(shè)備；技術(shù)監(jiān)督；知識圖譜

Abstract: Power grid enterprises have carried out technical supervision for many years and accumulated a large amount of data.Based on the current situation of data value, this paper proposed a multi-source data fusion method to construct the knowledge map of power grid technical supervision.This research also studied its ontology design, data extraction, knowledge fusion, and visual display.The application of power grid equipment technical supervision knowledge atlas realized intelligent retrieval question and answer and equipment family defect identification based on knowledge graph of technical supervision, which provides an idea for improving the digital management of power grid equipment.
Key words: multi-source data; power grid equipment; technical supervision; knowledge graph
