目前的电网必将发展成为由电力网和信息网组成的相互依存的复合网络.分析了智能电网网络构成的特点,阐述了信息网络安全在智能电网安全中的重要性.通过对智能电网信息化引入新元素的主要功能和特点的分析,从信息的采集、传输、处理和互动等角度描述了智能电网的信息安全问题,预想了各类攻击条件下的安全性事故场景.从网络功能的耦合性和网络间故障的传播特性探讨了信息网络安全对电力系统生存性的影响.最后,从关键技术、标准体系、政策法规、培训管理等方面提出了加强智能电网信息安全的具体建议,有助于提高智能电网安全性.

The present electric grids will definitely be developed into an intelligent power network interdependently composed of the power network and the information network. The characteristics of an intelligent power network are an alyzed and the importance of the information network security is emphasized. Various risks as well as malicious attack scenarios to the intelligent power network are analyzed from the aspect of information security, ranging from the informa tion collection, transmission, management and interaction. Furthermore, the impact from the emergency in the information network on the survivability of an intelligent power system is discussed based on the basic features of the coupling between the two networks. Proposals based on modern power system developments are given to enhance the information security of the intelligent power system in key technologies, standards, policies and training.
