摘　　要：根据电力企业的特点,系统分析信息共享与数据安全的重要性,在解决以往权限模型存在的缺陷和不足的同时,提出基于RBAC(RoleBasedAccessControl)改进模型的权限管理系统设计方案。该方案提出了静态责任区控制、动态责任区控制和运行参数的概念,对于保证模块级数据安全性、记录级数据安全性和变电站级数据辨识提供可行、可靠、高效的技术支撑,并从实用性角度详细分析该方案在三层C/S结构下的实现方法。According to the character of electric power enterprises, the importance of information share and data security is analyzed, the defect and deficient of old permission model is solved, at the same time the permission administration design scheme based on improved RBAC model is principally bringed forward that adduces the concept of static control of duty extent, dynamic control of duty extent and run parameters, gives a feasible, reliable, efficient technology sustain to improve the data security of module level, record level and ensure the data distinguish of substation level, explains the implementing method with three-tier C/S architecture deeply so that can offer a reference for practice.
