基于振动灰度图的DCGAN结合ResNet50的发电机故障诊断OA
Generator Fault Diagnosis Based on DCGAN of Vibrational Grayscale Image Combined with ResNet50
基于深度学习的故障诊断方法可以有效地实现发电机故障的智能诊断,但当训练样本过小或者样本分布不均匀时极易发生过拟合现象,影响模型的诊断效果和精度.为了解决上述问题,提出基于振动灰度图的深度卷积生成对抗网络(Deep Convolution Generative Adversarial Networks,DCGAN)结合残差网络(ResNet50)的发电机故障诊断方法,实现了在故障小样本与故障样本不均衡情况下的发电机故障智能诊断.最后通过对比实验证明,在发电机故障小样本或者故障样本不均衡情况下使用深度卷积生成对抗网络生成的故障样本对模型进行训练可以获得更高的诊断精度.
The fault diagnosis method based on deep learning can effectively realize the intelligent diagnosis of generator faults,but overfitting may occur easily when the training sample is too small or the sample distribution is not uniform,which affects the diagnosis effect and accuracy of the model.In order to solve these problems,this paper proposed a generator fault diagnosis method based on the deep convolutional generating adversal network(DCGAN)of vibrational grayscale image and residual network(ResNet50),which realizes the generator fault intelligent diagnosis under the condition of small fault samples and unbalanced fault samples.It was proved by experiment that the fault samples generated by DCGAN can be used to train the model in the case of small fault samples or unbalanced fault samples with higher diagnosis accuracy guaranteed.
