摘　　要：从"三层两网"架构、IEC61850标准体系、数据帧保护控制运行机制、模块化功能组织形态与高精度全网统一对时同步系统几方面分析了智能变电站继电保护架构体系,进而研究了智能变电站技术对继电保护的数据信息及保护原理、继电保护实现机制与架构体系、继电保护的设计、调试与运维的影响,最后展望智能变电站继电保护技术的发展方向。From the ＂three levels two nets＂ structure, IEC61850 standard, data frame protection control operation mechanism, modular function organization form and high precision unity prevailed over the synchronous system. This paper analyzes the relay protection framework system of smart substation through these several aspects, and then studies the impacts of smart substation on data and principles of relay protection, relay protection realization mechanism and structure system, relay protection design, commissioning, operation. Finally, the future research fields of relay protection in smart substation are summaried.
