摘　　要：随着信息系统的规模、复杂度和集成度的快速增长,信息系统可靠性面临诸多挑战,提高信息系统可靠性是亟待解决的问题。文章以国家电网有限公司集中部署的权限管理平台架构为研究对象,借鉴电力系统“双环网开环运行”模式,在不进行大规模改造的原则下,构建同城异地双活架构,以最优资源配比,提高信息系统的可靠性。研究成果已经在国网某省公司应用,经过试点验证,有效提升了架构性能,降低故障频率,形成了首个适应国家电网有限公司的信息系统可靠性保障典型架构模式,同时对其他信息系统架构可靠性提升具有普遍参考意义。With the rapid growth of the scale,complexity and integration of information system,the reliability of information system is facing many challenges.It is an urgent task to improve the reliability of information system.In this paper,the research object is the authority management platform framework centrally deployed by State Grid Corporation of China(SGCC).Referring to the mode of"double closed loop design and open loop operation"of power system,under the principle of small-scale transformation,we build a dual active framework in the same city and different places,and improve the reliability of information system with the optimal resource ratio.The research results have been applied in a provincial company of SGCC.Through the pilot verification,the architecture performance has been effectively improved and the failure frequency has been reduced.This paper has formed the first typical architecture mode of information system reliability assurance suitable for SGCC,and has universal reference significance for other information system architecture reliability improvement.
