基于边缘节点技术的电力系统入侵安全防护OA北大核心CSTPCD

To solve the problem of incomplete protection in power system security protection,a power system security pro-tection method based on edge node technology was designed.Firstly,based on the edge node technology,the edge multi-ac-cess computing model was established to implement data mi-gration for the power system and realize distributed data de-ployment.Secondly,the data transmission encryption al-gorithm was designed.And based on the GCForest,the power system network intrusion detection model,which was com-posed of a sample input layer,multi-granularity scanning layer,and training layer,was established to implement system intru-sion detection.The test results show that the average service delay of the proposed method is only 456.32ms,the network ro-bustness has no significant fluctuations,and the maximum false detection rate and missed detection rate of intrusion detection are 0.13%and 0.14%,respectively.
