Automatic defects diagnosis method for the relay protection device based on Apriori algorithm
Because the relay protection device operates for years and the large number of devices is large,its failure probability is relatively high,which brings a serious threat to the safe and stable operation of the power system.The automatic defect diagnosis method for relay protection device based on Apriori algorithm is proposed.Based on the Apriori algorithm,the device defect index set is constructed,the correlation indexes affecting the relay protection communication circuit are deeply analyzed,the identification model of the device fault defect is established,and the text of the device fault defect is identified.The experimental results show that the automatic defect diagnosis method of the relay protection device based on the Apriori algorithm can accurately diagnose the defect occurrence time of the excessively small rated current of the overcurrent protection device.
