HU Yan1,XIE Xiao-rong2,HAN Ying-duo2,XIN Yao-zhong3 (1.Nanjing Nari-Relays Electric Co., Ltd.,Nanjing 211100,Jiangsu Province,China;2.Department of Electrical Engineering,Tsinghua University,Haidian District,Beijing 100084,China;3.National Power Dispatch & Communication Centre,Xicheng District,Beijing 100031,China)  
Power information system is a large-scale, distributed, wide-areal, hierarchical system with numerous heterogeneous sub-systems, which security is multifactorial and multidimensional. So to design the security architecture of power information system, a systematic and structural design method and corresponding computer-aided tools are necessary. Here, the importance and present study situation of the design method for security architecture of power information system is expounded, the problems which may exist in the design of security architecture are analyzed in depth with respect to the uncertainty of security requirements and the dynamic and distributed characteristics of information systems. Finally, the requirements to the design method of the security architecture of power information system are put forward.
