Ethernet communication based on the IEC61850-line monitoring of electrical equipment IED

The IEC61850 defines two specific communication service mapping (SCSM) : IEC 61850-9-1-way multi-channel point-to-point specific services mapping and IEC 61850-9-2 process bus map for specific services to regulate the analog sample value (SAV) to achieve communication between the substation process layer and the spacer layer. From the sampled values of the communication protocol stack, service mapping and engineering application point of view, we comparatively analyse the feasibility and flexibility of the contradictions of the two standards. Combining with electrical equipment online monitoring IED, we construct object-oriented model Through pre-configured sampling control block transmission of sampled values model the flexible definition of the mapping scheme, it can achieve sampling data channel for engineering practical and flexible configuration, whose communication protocol is in line with IEC 61850-9-2. Through the LabVIEW programming for Ethernet communication tests to verify the reliability and practicability of the scheme.
