Basic Ied Functions; Station Communication - ABB Relion 650 Series Product Manual

Busbar protection REB650
Version 1.1 ANSI
• Status indication LEDs
• Alarm indication LEDs which can indicate three states
with the colors green, yellow and red, with user
printable label. All LEDs are configurable from the
PCM600 tool
• Liquid crystal display (LCD)
• Keypad with push buttons for control and navigation
purposes, switch for selection between local and remote
control and reset
• Five user programmable function buttons
• An isolated RJ45 communication port for PCM600

13. Basic IED functions

Self supervision with internal event list
The Self supervision with internal event list (INTERRSIG
and SELFSUPEVLST) function reacts to internal system
events generated by the different built-in self-supervision
elements. The internal events are saved in an internal
event list.
Time synchronization
Use time synchronization to achieve a common time base
for the IEDs in a protection and control system. This
makes comparison of events and disturbance data
between all IEDs in the system possible.
Time-tagging of internal events and disturbances are an
excellent help when evaluating faults. Without time
synchronization, only the events within the IED can be
compared to one another. With time synchronization,
events and disturbances within the entire station, and
even between line ends, can be compared during
evaluation.
In the IED, the internal time can be synchronized from a
number of sources:
• SNTP
• IRIG-B
• DNP
• IEC60870-5-103
Parameter setting groups ACTVGRP
Use the four sets of settings to optimize the IED
operation for different system conditions. Creating and
switching between fine-tuned setting sets, either from
the local HMI or configurable binary inputs, results in a
highly adaptable IED that can cope with a variety of
system scenarios.

Test mode functionality TESTMODE
The protection and control IEDs may have many included
functions. To make the testing procedure easier, the IEDs
include the feature that allows individual blocking of a
single-, several-, or all functions.
There are two ways of entering the test mode:
• By configuration, activating an input signal of the
function block TESTMODE
• By setting the IED in test mode in the local HMI
While the IED is in test mode, all functions are blocked.
Any function can be unblocked individually regarding
functionality and event signaling. This enables the user to
follow the operation of one or several related functions to
check functionality and to check parts of the
configuration, and so on.
Change lock function CHNGLCK
Change lock function (CHNGLCK) is used to block further
changes to the IED configuration and settings once the
commissioning is complete. The purpose is to block
inadvertent IED configuration changes beyond a certain
point in time.
Authority status ATHSTAT
Authority status (ATHSTAT) function is an indication
function block for user log-on activity.
Authority check ATHCHCK
To safeguard the interests of our customers, both the IED
and the tools that are accessing the IED are protected, by
means of authorization handling. The authorization
handling of the IED and the PCM600 is implemented at
both access points to the IED:
• local, through the local HMI
• remote, through the communication ports

14. Station communication

IEC 61850-8-1 communication protocol
The IED supports the communication protocols IEC
61850-8-1 and DNP3 over TCP/IP. All operational
information and controls are available through these
protocols. However, some communication functionality,
for example, horizontal communication (GOOSE) between
the IEDs, is only enabled by the IEC 61850-8-1
communication protocol.
