摘要

提出一种基于改进堆栈去噪自编码器（SDAE-SVM）的深度学习方法，用于高压电缆不同绝缘缺陷局部放电（PD）信号的模式识别。首先在高压实验室中对5种类型的人工缺陷进行PD测试，并提取3 500组PD瞬时脉冲，构建了34种特征参数。其次，详细介绍了SDAE-SVM的原理和网络架构。然后，使用所提模型识别不同缺陷类型的PD信号，获得了93.56%的识别精度。接着，使用t分布随机邻接嵌入（t-SNE）对SDAE-SVM逐层输出进行了可视化，说明了深度神经网络SDAE-SVM逐层优化的本质。最后，将所提方法与反向传播神经网络（BPNN）、支持向量机（SVM）和堆栈去噪自编码器（SDAE）进行了对比。结果表明，相比BPNN、SVM和SDAE、SDAE-SVM的总体识别精度分别提高了7.46%、6.70%、1.37%，具备较高的工程应用价值。

Abstract

A deep learning method based on an improved stacked denoising autoencoder (SDAE-SVM) is proposed for pattern recognization of partial discharge (PD) signals generated by different insulation defects in high-voltage cables. First

PD tests are conducted on five types of artificial defects in a high-voltage laboratory

and 3500 sets of PD instantaneous pulses are extracted to construct 34 types of characteristic parameters. Then

the principles and network architecture ofSDAE-SVMare introduced in detail. After that

the proposed model is used to recognize the PD signals of different types of defects and the pattern recognition accuracy of 93.56% is obtained. Moreover

the the layer-wise outputs of theSDAE-SVMare visualized using t-distributed stochastic neighbor embedding (t-SNE)

illustrating the essence of layer-wise optimization of the deep neural networkSDAE-SVM. Finally

the proposed method is compared with back propagation neural network (BPNN)

support vector machine (SVM) and stacked denoising autoencoders (SDAE) . The results show that compared with BPNN

SVM

and SDAE

the overall recognition accuracy ofSDAE-SVMhas increased by 7.46%

6.70%

and 1.37%

respectively

demonstraing high engineering application value .
