摘　　要：广域测量系统WAMS(Wide Area Measurement System)是新一代智能电网的重要组成部分,访问控制对于维护WAMS的系统安全十分重要。针对传统RBAC模型在复杂业务权限控制中的不足及WAMS中设备的特点,引入了被访问对象类型的属性和权限约束模块,对传统的RBAC模型进行改进。该模型使WAMS的访问控制更加灵活,角色管理更加方便。WAMS(Wide Area Measurement System)is an important part of the new generation of smart grid.Access control is very important to maintain the system security of WAMS.In view of the deficiency of the traditional RBAC model in the complex business permission control and the characteristics of the equipment in the Wide Area Measurement System(WAMS),the attribute and permission constraint modules of the accessed object types are introduced to improve the traditional RBAC model.This model makes the access control of WAMS more flexible and role management more convenient.
