针对我国配电电缆线路的运维存在缺失有效的状态监测体系及评估方法的问题,基于配电电缆的局部放电量、接头温度、载流量、直流分量四类结构化数据,提取时序数据模型与图像评价模型中softmax前一层特征进行融合,提出一种基于特征融合的中压配电电缆状态评估方法;最后采用某地实际数据验证了所提特征融合方法的有效性,该方法可以用于提高配电电缆差异化精准运维和决策指导支撑能力,综合提升配电电缆网运行安全水平与精益化管理技术支撑能力,助力配电网智能化升级和业务数字化转型取得突破.
Cable Status Evaluation Method Based on Feature Fusion
Aiming at the problem of lack of effective condition monitoring system and evaluation method in the op-eration and maintenance of distribution cable lines in our country,in the paper based on four types of structured data of local discharge,joint temperature,current carrying capacity and DC component of distribution cables,extracts the time-series data model and fuses the features of the previous layer of softmax in the image evaluation model,and proposes a feature fusion based condition evaluation method for medium voltage distribution cables;Finally,the ef-fectiveness of the proposed multimodal integration method is verified by the actual data validation of a certain place.This method can be used to improve the support ability of the distribution cable differential accurate operation and maintenance and decision-making guidance,comprehensively improve the operation safety level of the distribu-tion cable network and the support ability of lean management technology,and help the distribution network to a-chieve breakthroughs in intelligent upgrading and business Digital transformation.
