The Research Of IEC 61850 And Its Application In Fault Information Processing System

The IEC 61850 "Communication networks and system in substations" is the new international standard on substation automation. This thesis presents firstly the actuality of fault information processing system and the necessity of standardized construction., then introduces and analyzes the background, characteristics, content of IEC 61850 and its application in fault information processing system in detail. This thesis brings forward that the substation of a fault information processing system can be considered as an especial IED, whose construction is compliant with IEC 61850. The paper presents the object modeling approach of microcomputer-based protective relay according to IEC 61850. In addition, the implementation of seamless telecontrol communication architecture based on IEC 61850, migration from IEC 60870-5-103 to IEC 61850, unified object modeling approach with CIM of IEC 61970 are discussed.
