Basic Ied Functions; Station Communication - ABB Relion RES670 Product Manual

Phasor measurement unit RES670 2.1 IEC
• Graphical display capable of showing a user defined
single line diagram and provide an interface for
controlling switchgear.
• Navigation buttons and five user defined command
buttons to shortcuts in the HMI tree or simple
commands.
• 15 user defined three-color LEDs.
• Communication port for PCM600.
The LHMI is used for setting, monitoring and controlling.

16. Basic IED functions

Time synchronization
The time synchronization source selector is used to
select a common source of absolute time for the IED.
For RES670 as a Phasor Measurement Unit (PMU) an
accurate time synchronization is essential to allow the
comparison of phasors measured at different locations
in a Wide Area Monitoring System (WAMS). For an IED as
part of a protection system, time synchronization is
required to compare event and disturbance data
between all IEDs in a substation automation system. A
common source shall be used for IED and merging unit
when IEC 61850-9-2LE process bus communication is
used.
Only GPS and IRIG-B (Optical IRIG-B 00X is
recommended), with IEEE1344 support, are the
acceptable time synchronization sources for
synchrophasor measurement applications and RES670
supports both.

17. Station communication

Communication protocols
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.
Available communication protocols are:
• IEC 61850-8-1 communication protocol
• IEC 61850-9-2LE communication protocol
• LON communication protocol
• SPA or IEC 60870-5-103 communication protocol
• DNP3.0 communication protocol
• C37.118 communication protocol
Several protocols can be combined in the same IED.
IEC 61850-8-1 communication protocol
ABB
IEC 61850 Ed.1 or Ed.2 can be chosen by a setting in
PCM600. The IED is equipped with double optical
Ethernet rear ports for IEC 61850-8-1 station bus
communication. The IEC 61850-8-1 communication is
also possible from the electrical Ethernet front port. IEC
61850-8-1 protocol allows intelligent electrical devices
(IEDs) from different vendors to exchange information
and simplifies system engineering. IED-to-IED
communication using GOOSE and client-server
communication over MMS are supported. Disturbance
recording file (COMTRADE) uploading can be done over
MMS or FTP.
IEC 61850-9-2LE communication protocol
Single optical Ethernet port communication standard
IEC 61850-9-2LE for process bus is provided. IEC
M11344-3 v11
61850-9-2LE allows Non Conventional Instrument
Transformers (NCIT) with Merging Units (MU) or stand
alone Meging Units to exchange information with the
IED and simplifies SA engineering.
LON communication protocol
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 the IEDs.
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 IEC
60870-5-103 standard. This allows design of simple
substation automation systems including equipment
from different vendors. Disturbance files uploading is
provided.
M14815-3 v12 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 IEDs are used in Substation Automation systems
with LON, SPA or IEC 60870-5-103 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).
