| 摘要: |
| 由高压电缆不同类型缺陷诱发的局部放电(PD)的识别难度较大，尤其是某些相似度较高的电缆绝缘缺陷类型难以区分。提出了一种基于卷积神经网络(CNN)的高压电缆PD模式识别方法，研究了不同网络层数、不同激活函数以及不同池化方式对识别效果的影响，并与传统的支持向量机(SVM)和反向传播神经网络(BPNN)算法进行了对比。结果表明，相比SVM和BPNN, CNN的总体识别精度分别提高了3.71%和4.06%，且能较好地识别具有高相似度的电缆缺陷类型。 |

| Abstract: |
| The recognition of PD(Partial Discharge) caused by different types of defects in high-voltage cables is difficult, especially the recognition of PD caused by cable insulation defects with high similarity. The CNN(Convolutional Neural Network)-based PD pattern recognition method for high-voltage cables is presented. The influences of different network layers, activation functions and pooling methods of CNN on recognition effect are studied. The proposed method is also compared with SVM(Support Vector Machine) and BPNN(Back Propagation Neural Network) method, and the results show that the overall recognition accuracy of CNN is respectively 3.71% and 4.06% higher than that of SVM and BPNN. Furthermore, it is proved that the cable insulation defects with high similarity can be effectively recognized by CNN. |
