近年来,电网信息化进程明显加快,能源互联、泛在智能、主动配网等战略的推进,进一步提升了电网信息化、自动化、互动化程度,使实体电网与信息通信网络更加相互依存和交融,而保障实体电网的安全就必须保障信息通信的安全。信息通信的安全防护直接影响实体电网的安全。2016年1月,乌克兰电力系统遭网络黑客攻击导致乌克兰西部地区大规模停电。黑客通过恶意代码邮件窃取了乌克兰电力部门的计算机信息,侵入变电站调度控制和电话系统,控制断路器跳闸,造成7个 In recent years, the informatization of power grid has obviously accelerated. The promotion of energy interconnection, ubiquitous intelligence and active distribution network further promoted the informatization, automation and interaction of power grids and made the interdependence and integration of physical power grid and information and communication network more substantial , While ensuring the security of the physical power grid must guarantee the security of information and communication. The security of information and communication directly affects the security of the physical power grid.
