An error recognition method for power equipment defect records based on knowledge graph technology

Next Previous

Abstract

To recognize errors in the s in real time, we propose an method based on technology. According to the characteristics of s, a method for constructing a of power equipment defects is presented. Then, a graph search algorithm is employed to recognize different kinds of errors in defect records, based on the of power equipment defects. Finally, an example in terms of transformer defect records is given, by comparing the precision, recall, -score, accuracy, and efficiency of the proposed method with those of methods, and the factors influencing the effects of various methods are analyzed. Results show that the proposed method performs better in of defect records than methods, and can satisfy real-time requirements.
