Abstract: In order to effectively solve the suboptimal problems of comprehensive information security based on power system,this paper combined with the specific environmental of power system,and designed a comprehensive evaluation architecture of information security.This architecture links these variable factors that contain technology,management,strategy,system,monitor,and evaluates the develope synergistic degree of these variable factors.Analysis shows that only ensuring synergetic development of these variable factors can optimize the information security level of power system efficiently.

Key words: Information security,Synergetics,Evaluation architecture,Power system
