摘　　要：由于复杂环境下的光纤复合架空地线(OPGW)长期受到环境变化的作用,光缆结构中的光纤、金属单线、油膏和光单元管等部分会遭受不同程度的影响,最终导致电力通信故障。提出一种基于环境参量和主成分分析的OPGW光缆状态风险评估方法,根据架空线路中光纤光栅传感器采集的环境参数,采用主客观权重法和主成分分析法对OPGW光缆的状态进行评估,数据分析结果表明该方法可以有效反映OPGW光缆的运行状态。As the optical fiber composite overhead ground wire(OPGW)in a complex environment will be affected by environmental changes for a long time,and the optical fiber,metal single wire,grease and optical unit tube in the optical cable structure will be affected to varying degrees,eventually leading to power communication failure.A risk assessment method for OPGW optical cable status based on environmental parameters and principal component analysis is proposed.According to the environmental parameters collected by fiber grating sensors in overhead lines,subjective and objective weighting method and principal component analysis are used to evaluate the OPGW optical cable status and data analysis.The data analysis results show that this method can effectively reflect the operating status of OPGW optical cable.
