The Research, Realization And Application Of Iec61850 Control Class Model

5578

Control Model is an important function in Substation Automation System to control the device from remote. IEC61850 uses the abstract communication service interface (ACSI) and specific communication service mapping (SCSM) definition method. Most of data structure and communication service are mapping to Manufacturing Message Specification (MMS), but MMS has high abstraction, many 61850 ACSI services are mapping to one mms service [6]. At the same time there are many fuzzy definitions even mapping deviation phenomena, different vendors may have inconsistent understanding to the standard, this is harmful to the conformance and interoperability. This paper provide analysis and comparison to the 61850 Control Class model and based on these, gives realization based on mms-ease-lite for the first time, and also gives application of control class model and detailed explanations of actual telegram for the first time. Our research is very helpful to eliminate understanding difference and achieve interoperability. System test uses popular software to simulate as server, and the widely used network protocol analyzer software Omicron IEDScout is used to capture packets, the result verifies our implementation satisfy the functionality, conformance and interoperability.
