To address the difficulty of data association in power grid projects,a knowledge graph tech-nology based data association analysis for power grid projects is proposed.The feature extraction methods for historical projects and newly added reserve projects are analyzed,the rule-based information extraction and sequence annotation-based information extraction methods are discussed,the basic composition and construction methods of knowledge graph for power projects are discussed,a multi-dimensional associa-tion analysis platform for projects is proposed,the analysis methods and processes are discussed,and a sys-tem network structure is proposed.Combined with practical applications,this paper explained the system's application effect in tag extraction.
