基于自主可控式的变电站移动化业务的信息安全防护设计与应用OACSTPCD

Considering the actual situation of mobile business applications in substations,this paper constructs a power Wi-Fi private network.Authentication,encryption,isolation and other technical measures,edge IoT proxy and other modes are adopted to achieve the mobility of multiple types of business in substations.The business data streams are transmited through the Wi-Fi private network to solve the problems such as weak signal or inability to connect to the network at substation terminals,the mobile application ability and security defense effectiveness of power enterprises are effectively improved.The results prove that the technical achievements in this paper have a promoting effect on the practicality of power grid mobile business,effectively ensuring network security,and significantly improving work efficiency.
