基于知识图谱的分布式光伏运维方案匹配方法

Matching method for distributed photovoltaic maintenance scheme based on knowledge graph

为了提高分布式光伏运维效率,设计了一种利用专业领域知识图谱匹配运维方案的方法。该方法基于运维诉求与分布式光伏运维知识图谱中的信息,匹配准确的运维方案,为运维人员提供方案支持。首先陈述了在单一故障、诉求完整的状况下以知识图谱为媒介匹配运维方案的方法;再基于复合型运维诉求设计了先拆分诉求再分别匹配的流程;然后针对实践中诉求要素缺失的问题,利用知识图谱提供的联想能力,使该方法能够补全诉求并匹配方案。实验对比分析表明,该方法准确度较高,并且在实践中具有理想的可靠性。

To improve the efficiency of distributed photovoltaic maintenance industry,a matching method for maintenance scheme based on professional domain knowledge graph was designed.The maintenance scheme based on maintenance requirements and the distributed photovoltaic maintenance knowledge graph was matched accurately,which provided scheme support for maintenance personnel.A method of matching maintenance scheme with the knowledge graph as a bridge was presented.The matching process was improved according to the complex type of maintenance requirements.In view of incomplete requirements in practice,the method was enabled to match the scheme by inference with the knowledge graph.Experiments showed that the improved approaches helped to provide a higher degree of accuracy and better reliability.
