APPENDIX H: IEC 61850 COMMUNICATIONS
F EATURES
The SEL-387E relay supports the following features using Ethernet and IEC 61850:
• SCADA—Use as many as six MMS sessions of buffered and unbuffered reports.
Remote Bits (RB1–RB6) and CC (Close Command) bits are mapped to the CSWI logical
node. See the CC bit in
Table H.8, and the Control column in Table H.10 for details on
which logical nodes and names are used for these bits. This information can be useful
with MMS browsers. Assertion of a CC control input will assert the SEL-387E CC bit
and deassert the OC (Open Command) bit. Control inputs only support the direct-with-
normal-security control model.
• Real-Time Status and Control—Use GOOSE with as many as 16 incoming (receive)
and as many as 8 outgoing (transmit) messages. Controls only support the direct-with-
normal-security control model.
Remote Bits (RB1–RB16), Open Command bits (OC1–OC3) and Close Command bits
(CC1–CC3) can also be mapped from GOOSE receive messages using
AC SEL ERATOR
®
Architect
™
SEL-5032 software. GOOSE provides separate bits for opening and closing
the breaker since GOOSE repetitively sends the same information, which could
inadvertently open or close a breaker if only a single bit was provided.
• Configuration—Use FTP client software or
AC SEL ERATOR Architect to transfer the
Substation Configuration Language (SCL) Configured IED Description (CID) files to the
relay.
• Commissioning and Troubleshooting—Use software such as MMS Object Explorer
and AX-S4 MMS from Sisco, Inc., to browse the relay logical nodes and verify
functionality.
Note: The SEL-387E supports one CID file, which should be transferred only if a
change in the relay configuration is required. If an invalid CID file is
transferred, the relay will no longer have a valid IEC 61850 configuration, and
the protocol will stop operating. To restart protocol operation, a valid CID must
be transferred to the relay.
• Firmware Upgrades—Use FTP client software to transfer the Ethernet port firmware
upgrade file to the relay.
