摘要绝缘子是输电线路上的重要设备,其运行状况直接影响到电网的安全运行,因此对绝缘子状态自动、准确地检测是十分重要且必要的。针对已有检测模型处理不同样本时采用固定特征空间的不足及现有绝缘子检测算法特征提取复杂的缺陷,模仿人类由简到细反复推敲比对的认知过程,探索一种基于反馈机制的卷积神经网络绝缘子状态检测方法。首先,针对绝缘子样本的特点,改进LeNet_5网络结构,引入随机配置网络分类器,添加反馈机制调节卷积核的大小和个数,采用交替优化的策略以优化卷积神经网络的参数。其次,基于熵理论,建立语义误差信息熵测度评价指标,实时评价绝缘子不确定检测结果,克服状态后验评测的缺陷。最后,依据语义误差信息熵测度指标评价结果,通过构建的反馈机制调节卷积核的大小和个数细化提取特征,从而实现由简到细反复推敲比对优化检测结果。实验结果表明,改进型卷积神经网络模型在绝缘子状态检测上具有较高的检测正确率。

Abstract：As an important equipment on the transmission line, the conditions of insulators directly affect the safe operation of power grid. Therefore, it is important and necessary to detect the insulator state automatically and accurately. However, existing detection models with constant feature space have drawbacks for distinctive samples, and it is complex to extract insulator image features. Thus, a method for insulator state detection based on convolutional neural network and feedback mechanism is explored in this paper, which imitates the human cognition process with repetitive comparison and inference from simple to fine. Firstly, according to the characteristics of the insulator samples, the network structure of LeNet-5 is improved by employing stochastic configuration networks (SCNs) and the feedback mechanism, and the alternate optimization strategy is adopted to optimize the parameters of the convolution neural network. Secondly, based on the entropy theory, the semantic error entropy measurement index is established to evaluate the uncertainty of the insulator detection results in real time to overcome the posterior evaluation. Finally, according to the evaluation results of semantic error information entropy measurement index, the feedback mechanism is constructed to adjust the size and number of the convolution kernels to extract the refined features for the repeated comparison and inference. The experimental results show that the improved convolution neural network model has a superior accuracy in insulator state detection.
