摘　　要：现有电网故障分析策略不能实现多源故障数据综合分析,导致电网故障诊断的自动化水平滞后。提出一种多源故障数据融合方法:基于集对分析理论对多源故障数据进行相关性分析,对反映同一故障事件的可靠数据信息进行整合,建立基于COMTRADE文件格式的多源数据模型,并采用蛮力BF算法对各数据源进行时间对齐,实现多源故障数据信息融合。实测案例验证了所提方法的有效性,且方法有助于大规模电网故障数据的统一管理及有效分析,可提升电网故障分析水平和效率。Existing power grid fault diagnosis strategies can not analyze the multi-source failure data from a global perspective, resulting in a relatively lagged automatization of power grid fault diagnosis. Therefore, a multi-source fault data comprehensive analysis method is proposed in this paper. Firstly, correlation analysis of multi-source fault data is performed with a unified COMTRADE expression model constructed to obtain and integrate reliable information reflecting the same fault event. Then with BF time alignment method applied, the efficient integration of multi-source fault data is realized, which helps to achieve unified management and effective analysis of large-scale grid fault data. The application case verifies the effectiveness of the proposed method.
