随着智能变电站工程的发展，阐述了SCD在实现智能变电站中的特点作用和对SCD管理的本质要求。分析了SCD二次回路“离线、在线、实时”监控的前提条件和效用，以及基于IEC61850的实施项目中可配置IED与指定IED的主要区别。分析了基于不同类型继电器的SCD监测方法的特点，并提出了辅助方法。最后，提出了未来SCD“设计、组态、运行”一体化监控的技术方案。
With the development of smart substation project, the feature role of SCD in the implemented smart substation and the essential requirement of SCD management are illustrated. The paper analyzes the precondition and utility of "offline, online and real time" secondary circuit monitoring of SCD, and the main difference of configurable IED and specified IED in the implemented project based on IEC61850. The characteristic of different SCD monitoring methods based on the different kinds of relays are analyzed, and the assistant approaches are mentioned. Finally, this paper proposes the technical scheme of SCD "design, configuration, operation" integrated monitoring in the future.
