The GOOSE Departs

by Walter Schossig, Germany, and Thomas Schossig, OMICRON electronics GmbH, Austria

In the last issue the way to IEC 61850 was described. We explained the activities of UCA and EPRI, covered MMS. Ethernet entered the substation and first interoperability events took place. The discussion was not only about the protocol to be used, but also for the data modeling. Under auspices of the EPRI UCA the Generic Object Models for Substation and Feeder Equipment (GOMSFE) have been developed.  The goal of GOMSFE was to facilitate vendors in implementing the UCA substation and feeder elements of the power system into a product design. It did not, however, describe the mapping of the objects onto the application layer. This mapping was described in the UCA 2.0 Common Application Services Model and Mapping to MMS (CASM). The building blocks, or “bricks” modeled in GOMSFE are aggregated to form the logical device models that are contained by the remote server and represent real world devices. More
