Abstract:

Aiming classifying the power quality disturbance (PQD),a PQD classification method based on Gramian Angular Field (GAF) and transfer learning proposed.First,GAF is used to convert one-dimensional PQD signal data into two-dimensional pictures.Then,the generated pictures are trained and classified by the improved transfer learning model AlexNet,and the PQD classification is completed.Finally,the IEEE 14 model is used to simulate different types of PQD signals,and the proposed mothod is verified.The results show that the proposed method is effective.

Key words: power quality, disturbance classification, gram matrix, transfer learning
