为提升输电线路故障巡检、运维效率和线路智能化水平,提出了基于知识图谱的输电线路故障识别与位置定位技术.首先,采用长短记忆网络+条件随机场进行实体抽取,关系抽取采用依存句法分析得到相应的三元组结构数据,采用基于事件框架的方法进行事件抽取;其次,分别采用文本和实例相结合的方法和基于实体对齐概率模型的方法构建本体层和数据层,实现输电线路故障原因的快速查询和故障位置的准确定位;最后在此基础之上搭建智能问答系统.所提系统能够快速对输电线路相关设备故障进行分析,提高了输电线路故障巡检、运维的效率,保障了输电线路运行的可靠性.
Research on Transmission Line Fault Identification and Location Technology Based on Knowledge Graph
In order to improve the efficiency of transmission line fault inspection,operation and maintenance,and the level of line intelligence,a knowledge graph-based transmission line fault identification and location positioning technology was proposed.Firstly,entity extraction was carried out using long and short memory networks and conditional random fields.Relationship extraction used dependency syntax analysis to obtain corresponding triplet structured data,and event extraction was carried out using an event framework based method;secondly,the ontology layer and data layer were constructed using a combination of text and instance methods,as well as an entity alignment probability model based method,to achieve rapid query of transmission line fault causes and accurate positioning of fault locations;finally,an intelligent question answering system was built on this basis.The proposed technical system can quickly analyze equipment faults related to transmission lines,improve the efficiency of transmission line fault inspection and operation maintenance,and ensure the reliability of transmission line operation.
