摘要
随着智能电网和跨区稳定控制技术的发展,信息通信与电力系统的耦合更加紧密,网络攻击带来的安全风险也越来越高。稳控系统E1通道作为重要的测控通道,其安全性对稳控系统起到重要的作用,因此,开展面向稳控系统E1通道的半实物仿真和攻防演练,对发现E1通道的安全漏洞有重要意义。首先,基于半实物仿真技术设计了面向稳控系统E1通道的网络靶场实验台,介绍基于该实验台的攻防演练方案;然后,通过该实验台对一个典型的在运稳控系统E1通道开展仿真和攻击模拟实验,测试了稳控系统的安全隐患,并验证了实验台的有效性;最后,提出几种提升E1通道安全性的方法,并展望了实验台的应用前景。
With the development of smart grid and trans-region stability control technology,the information communication and the power system is being coupled more closely,and the security risk caused by cyber-attack is becoming higher and higher.As a key measurement and control channel,the E1 channel of the stability control system plays an important role for the security of stability control system.Thus,it is of significance to conduct the attack and defense drills on a hardware-in-the-loop simulation platform to find the security risk of E1 channel of the stability control system.Firstly,a cyber range testbed was designed for the E1 channel of the stability control system based on the hardware-in-the-loop simulation technology,and the scheme of attack and defense drills on the designed testbed was briefly introduced.Then,through the testbed,we simulated a case of a cyber-attack on the E1 channel of an operating power stability control system to test its security risk and validate effectiveness of the designed testbed.Finally,we proposed several solutions to improve the security of the E1 channel,and made a perspective of the future application of the designed testbed.
