With the development of smart substation project, the feature&role of SCD in the implemented smart substation and the essential requirement of SCD management have beenare illustrated. The paper analyzes the precondition and utility of“offline, online and real time”secondary circuit surveyc 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 survey monitoring methods based on the different kinds of relays has beenare analyzed, and proposed the assistant approaches have beenare mentioned. Finally, the authoris paper proposes the technical scheme of SCD“design, configuration, operation”integrated survey monitoring in the future.
