摘　　要：光纤复合架空地线(OPGW)在运行中受到内外条件的影响,结构中的金属绞线、油膏、光单元管和光纤等部分将发生一定程度的性能退化,导致光缆整体的健康度恶化。如何根据不同的参量对OPGW光缆的健康度状态进行评估,在故障发生之前进行维修或更换,是当下面临的主要问题。文章提出了基于主客观权重赋值法和主成份分析(PCA)法的OPGW光缆健康度评估方法,并进行了算例分析。数据分析结果表明,文章所提方法可有效地反映OPGW光缆的健康度状态。Under the influence of internal and external conditions during the peration of Optical Fiber Composite Overhead Ground Wire(OPGW),the performance of metal strand,ointment,optical unit tube and optical fiber in the structure will degrade to a certain extent,resulting in the deterioration of the overall health of optical cable.How to evaluate the health status of OPGW optical cable according to different parameters and repair or replace it before failure is the main problem.In this paper,a health evaluation method of OPGW optical cable based on subjective and objective weight assignment method and Principal Component Analysis(PCA)method is proposed with detailed case analysis.The data analysis results show that this method can effectively reflect the health status of OPGW optical cable.
