Analysis And Implementation On Line Bay Based On IEC 61850

Substation automation system in the power system has been widely used, but also has played an important role for the protection of power grids.In light of the many substation automation system inadequate, the International Electrotechnical Commission promulgated by international standards - substation communications network and system IEC 61850, it is to build digital communications network and substation provides a standardized system. This paper accomplished the configuration of the IED and Communication launched in-depth study.Initially based on the IEC 61850 standard architecture and idea, summed up IEC 61850 is application-oriented functions with a self-description of the substation communication standards, expatiated the technical characteristics and the influence of protection.Second,IED line spacing will be followed by the application of functional decomposition for the relevant logic nodes, and the establishment of an information logic model of the data node object, attribute data and related services. It was expatiated that XML Schema definition of the structure of the SCL model, and model components in the preparation principles, and protection against line spacing information model configuration.Finally, the abstract communications services interface (ACSI), and manufacturing message specification (MMS), as well as the mapping between the two were analyzed and summarized the mapping type. Design a universal server software platform to complete the various types of mapping.Based on ACSI+MMS+TCP/IP+ Ethernet network communications transmission, and third-party tools——MMS message analysis software verification achieved ACSI model in the services category.
