| Abstract: | In order to ensure the stable operation of large-scale power communication equipment connected into the power grid,the physical model of communication equipment was analyzed,and the influencing factors and defect characteristics of power communication equipment defects and the mapping relationship between them were analyzed.The Apriori algorithm was improved to reduce the time complexity and memory space of algorithm.The defect data model of power communication equipment was imported and the association rules were combined to propose a correlation analysis method of power communication equipment defect based on the improved Apriori algorithm.The results showed that there existed the frequent defective item sets in the power communication equipment,and there was a strong correlation with the influencing factors.Finally,the effectiveness of the method was verified by a simulation calculation example with the defect data of actual power communication equipment,which provides support for the formulation of communication maintenance strategies. |
