摘　　要：在过往传统的电力系统通信保护中,由于链路占用率长期无法平衡,使得通信网络安全性不足,易受到来自外部的攻击。基于此,设计了一种应用虚拟专用网络(Virtual Private Network,VPN)技术的电力系统通信自动保护体系,通过阐述电力系统通信自动保护需求,提出电力系统通信自动保护方法,并详细叙述了VPN技术的应用模型。最后对设计出的保护体系进行了实例分析,探索VPN技术应用后保护体系的应用效果,结果证明,应用了VPN技术的电力系统通信自动保护体系的链路占有率更加平衡,受到外部攻击的概率更小,其网络安全性得到了较大的提升。In the traditional power system communication protection,because the link occupancy can not be balanced for a long time,the communication network security is insufficient,vulnerable to external attacks.Based on this,this paper designs a power system communication automatic protection system using Virtual Private Network(VPN)technology,and expounds the requirement of power system communication automatic protection,an automatic protection method for power system communication is proposed and the application model of VPN technology is described in detail.Finally,the protection system designed by the example analysis,to explore the application of VPN technology after the application of the protection system,the results prove that,the link occupancy of power system communication automatic protection system with VPN technology is more balanced,the probability of being attacked is less,and the network security is improved greatly.
