SECTION 17
IEC 61850 Communication
The relay supports the following features using Ethernet and IEC 61850.
➤ SCADA—Connect as many as seven simultaneous IEC 61850 MMS
client sessions. The relay also supports as many as seven buffered
and seven unbuffered report control blocks. See Table 17.16 for
logical node mapping that enables SCADA control (including Setting
Group Switch) via a manufacturing messaging specification (MMS)
browser. Controls support the Direct Normal Security and Enhanced
Security (Direct or Select Before Operate) control models.
➤ Peer-to-Peer Real-Time Status and Control—Use GOOSE with as
many as 128 incoming (receive) and 8 outgoing (transmit) messages.
Virtual Bits (VB001–VB256) and Remote Analogs (RA001–RA256)
can be mapped from incoming GOOSE messages. Remote Analog
Outputs (RAO01–RAO64) provide peer-to-peer real-time analog
data transmission.
NOTE: Not all SEL-400 series relays
support SV publication or
subscription.
➤ Sampled Values—Use Sampled Values (SV) to replace the
traditional copper wiring between instrument transformers and the
relay. Connect an SEL SV publisher to CTs and VTs to publish
Sampled Values. Use SV subscriber relays to subscribe to these SV
messages. SEL-400 series SV products are compliant to the
UCA 61850 9-2LE guidelines. In accordance with the guideline,
each publication includes one application service data unit (ASDU),
with four current and four voltage channels. Supported publication
rates are 4.8 kHz for a 60 Hz power system and 4 kHz for a 50 Hz
power system. SEL SV publishers support as many as seven SV
streams. SEL SV subscriber relays support subscribing to as many as
seven streams.
NOTE: The relay ships with a default
CID file installed which supports basic
IEC 61850 functionality. A new CID file
should be loaded if a change in the
relay configuration is required. If an
invalid CID file is transferred, the relay
will reject the file and revert to the
previous valid CID file.
➤ Configuration—Use FTP client software or ACSELERATOR
Architect SEL-5032 Software to transfer the Substation
Configuration Language (SCL) Configured IED Description (CID)
file to the relay. SEL-400 series SV products also support SV
configuration via Port 5 settings.
➤ 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.
