摘要
The real-time monitoring of the substation equipment plays an important role in the safe and stable operation of the power grid. To realize the fast and accurate recognition of the substation equipment under complex background environments, a method of infrared image recognition based on the lightweight YOLOv5 is proposed. The introduction of the Ghost convolution in the back-bone network makes the network lighter and the detection speed significantly improved. An attention module based on the information interaction strategy between the channels is added to eliminate the interference of the irrelevant information and improve the saliency of the target. In the feature fusion stage, the improved C3 module with self-attention is utilized to enhance the feature capture ability and improve the network accuracy. In addition, the Cluster NMS (non-maximum suppression) and the EIOU(efficient intersection over union) loss are introduced to accelerate the network convergence. Tests are performed on the data sets containing three types of the substation equipment. The recognition accuracy reaches 93.80% with the detection speed as 0.0011s per picture ideally. Compared with the four classical networks, the experimental results show that the proposed algorithm reduces the average time consumption by 5.42% while improving the accuracy effectively and the storage size of the model is decreased by 26.38 %, which meets the requirements for the accuracy and real-time recognition of the substation equipment, providing conditions for the subsequent equipment fault diagnosis. © 2023 Power System Technology Press.
