变电站网络安全及应对方案研究

Research on Network Security and Response Options of Substation

随着电力系统信息化建设的不断深入,网络通信技术在变电站建设当中扮演着越来越重要的角色,信息化技术为实现变电站智能化创造了良好的条件,但是不断加剧的网络安全形势对自动化通信技术提出了新的挑战。综合变电站的建设发展现状,该文就变电站网络结构的常见安全问题进行分析,针对性地提出了本体加固技术、数字签名技术、入侵检测技术和通信安全等对策,以期解决变电站网络安全问题。

With the deepening of power system information construction,network communication technology plays an important role in substation construction.Information technology creates good conditions for the realization of substation intelligence,but the increasing network security situation puts forward new challenges to automatic communication technology.Based on the current situation of substation construction and development,this paper analyzes the common security problems of substation network structure,and puts forward countermeasures such as ontology reinforcement technology,digital signature technology,intrusion detection technology and communication security to solve the network security problems of substation.
