17. Station communication

Overview
Each IED is provided with a communication
interface, enabling it to connect to one or many
substation level systems or equipment, either on
the Substation Automation (SA) bus or Substation
Monitoring (SM) bus.
Following communication protocols are available:
• IEC 61850-8-1 communication protocol
• LON communication protocol
• SPA or IEC 60870-5-103 communication
protocol
• DNP3.0 communication protocol
Theoretically, several protocols can be combined
in the same IED.
IEC 61850-8-1 communication protocol
The IED is equipped with single or double optical
Ethernet rear ports (order dependent) for IEC
61850-8-1 station bus communication. The IEC
61850-8-1 communication is also possible from
the optical Ethernet front port. IEC 61850-8-1
protocol allows intelligent electrical devices (IEDs)
from different vendors to exchange information
1MRK 504 117-BEN D
and simplifies system engineering. Peer-to-peer
communication according to GOOSE is part of
the standard. Disturbance files uploading is
provided.
Serial communication, LON
Existing stations with ABB station bus LON can
be extended with use of the optical LON
interface. This allows full SA functionality including
peer-to-peer messaging and cooperation
between existing ABB IED's and the new IED 670.
SPA communication protocol
A single glass or plastic port is provided for the
ABB SPA protocol. This allows extensions of
simple substation automation systems but the
main use is for Substation Monitoring Systems
SMS.
IEC 60870-5-103 communication protocol
A single glass or plastic port is provided for the
IEC60870-5-103 standard. This allows design of
simple substation automation systems including
equipment from different vendors. Disturbance
files uploading is provided.
DNP3.0 communication protocol
An electrical RS485 and an optical Ethernet port
is available for the DNP3.0 communication. DNP3.
0 Level 2 communication with unsolicited events,
time synchronizing and disturbance reporting is
provided for communication to RTUs, Gateways
or HMI systems.
Multiple command and transmit
When 670 IED's are used in Substation
Automation systems with LON, SPA or
IEC60870-5-103 communication protocols the
Event and Multiple Command function blocks are
used as the communication interface for vertical
communication to station HMI and gateway and
as interface for horizontal peer-to-peer
communication (over LON only).
IEC 62439-3 Parallel Redundant Protocol
Redundant station bus communication according
to IEC 62439-3 Edition 1 and IEC 62439-3 Edition
2 are available as options in 670 series IEDs. IEC
62439-3 parallel redundant protocol is an optional
quantity and the selection is made at ordering.
Redundant station bus communication according
to IEC 62439-3 uses both port AB and port CD
on the OEM module.
