摘　　要：随着传感元件和通信设备在电力系统中的广泛应用,现代电力系统已经成为高度依赖通信网络的信息物理融合系统。信息化程度的提高不仅增强了系统实时感知与动态控制的能力,也加剧了系统遭受恶意网络攻击的风险,近年来频繁发生的网络攻击事件已为国际社会敲响警钟。目前,国内外的研究主要集中在网络攻击的建模、防御与评估,缺乏对网络攻击影响过程的研究。据此首先分析了网络攻击对发、输、配、用电侧典型场景的影响,对每个场景的物理特性和结构进行建模,并在此基础上评估了电力系统遭遇网络攻击时的脆弱性,然后阐释了电力系统在网络攻击下的响应过程和网络攻击的破坏效果,最后对现有的研究进行了总结与展望。With the widespread application of sensing elements and communication devices in power systems,modern power systems have become a cyber-physical integration system which is highly dependent on the communication networks.The improvement of informationization degree not only enhances the real-time perception and dynamic control capability of the system,but also increases the risk of cyber attacks on power systems.The frequent cyber attacks in recent years have sounded the alarm for the international community.At present,the research on cyber attacks in China and abroad is mainly focused on the modeling,defense and evalua-tion.The research on the entire process influence of cyber attack is still in its infancy.This paper analyzes the impact of cyber attack on typical power system scenarios of generation,transmission,distribution and user side.Firstly,the physical characteristics and structure of each scenario are modeled,and the vulnerability of the scenario subject to cyber attacks is evaluated after that.Then the response of the system under the cyber attack and the destructive effect of the cyber attack are analyzed.Finally,the existing research is summarized and prospected.
