Abstract: With the continuous improvement of the integration level of the power system, the information security risks it facing increased contrast, how to comprehensive evaluate information security of integrated platform becomes the key issue to improve the level of business applications. Aiming at complex system architecture for the integration of information integrated platform, this paper studies information safety assessment index system modeling using Fuzzy Analytic Hierarchy Process(FAHP) and improved D-S evidence theory, puts forward a set of information security integrated platform rating system. It takes a regional of Guangdong province metering automation system for instance, to verify the feasibility and effectiveness of the information security level assessment system.

Key words: Fuzzy Analytical Hierarchy Process(FAHP), D-S theory, integrated platform, information security, safety assessment, metering automation

摘要： 电力系统一体化水平的不断提高使其面临的信息安全风险随之增加，如何对一体化平台进行信息安全的综合评估成为提高业务应用水平的关键问题。为此，针对一体化信息集成平台复杂的系统架构，对信息安全评估指标体系进行建模，运用模糊层次分析法和改进的D-S证据理论，设计基于一体化平台的信息安全等级评估体系。以广东省某地区计量自动化系统为实例，验证了该信息安全等级评估体系的可行性和有效性。
