In the process of power system network intrusion detection,the image is converted from the RGB space domain to the HSV space domain,and the V component is used to process it,and then the enhanced image is output from RGB under the operation of decomposition,enhancement and noise reduction,which is used as an important condition for the realization of power equipment state awareness,and lays a solid foundation for the subsequent power system network intrusion detection.Based on the improved Retinex-Net,the research on the power system network intrusion detection method aims to enhance the network and improve the fault detection ability of the power system network by using the end-to-end trainable low-brightness image of Retinex-Net,so as to form an efficient power system network intrusion detection method.
