摘要

电力二次设备是保证电力系统安全和稳定性的屏障，提高其生命周期各阶段的信息利用率，能更加全面地评价设备质量。文章将二次设备全生命周期中各类数据进行预处理，通过领域术语特性分析，制定标注规范及规则，建立领域专业语料库，构建电力二次设备全生命周期领域本体。利用图数据库实现领域知识图谱存储，完成领域知识图谱构建，实现节点及关系的知识查询，整合了电力二次设备全生命周期的碎片化信息，打破各阶段的信息孤岛。

Abstract

Power secondary equipment is a barrier to ensure the safety and stability of power system. It can improve the information utilization rate of each stage of its life cycle and evaluate the quality of equipment more comprehensively. In this paper

all kinds of data in the whole life cycle of secondary equipment are preprocessed. Through the analysis of the characteristics of domain terms

the labeling specifications and rules are formulated

the domain professional corpus is established

and the domain ontology of the whole life cycle of power secondary equipment is constructed. Using the graph database to realize the storage of domain knowledge graph

complete the construction of domain knowledge graph

realize the knowledge query of nodes and relationships

integrate the fragmented information of the whole life cycle of power secondary equipment

and break the information island of each stage.
