to all events, which are continuously saved in a -buffer. The
local HMI is used to get information about the recordings. The
disturbance report files may be uploaded to PCM600 for
further analysis using the disturbance handling tool.
Event list DRPRDRE
Continuous event-logging is useful for monitoring the system
from an overview perspective and is a complement to specific
disturbance recorder functions.
The event list logs all binary input signals connected to the
Disturbance recorder function. The list may contain up to
1000 time-tagged events stored in a -buffer.
Indications DRPRDRE
To get fast, condensed and reliable information about
disturbances in the primary and/or in the secondary system it
is important to know, for example binary signals that have
changed status during a disturbance. This information is used
in the short perspective to get information via the local HMI in
a straightforward way.
There are three LEDs on the local HMI (green, yellow and
red), which will display status information about the IED and
the Disturbance recorder function (triggered).
The Indication list function shows all selected binary input
signals connected to the Disturbance recorder function that
have changed status during a disturbance.
Event recorder DRPRDRE
Quick, complete and reliable information about disturbances
in the primary and/or in the secondary system is vital, for
example, time-tagged events logged during disturbances.
This information is used for different purposes in the short
term (for example corrective actions) and in the long term (for
example functional analysis).
The event recorder logs all selected binary input signals
connected to the Disturbance recorder function. Each
recording can contain up to 150 time-tagged events.
The event recorder information is available for the
disturbances locally in the IED.
The event recording information is an integrated part of the
disturbance record (Comtrade file).
Trip value recorder DRPRDRE
Information about the pre-fault and fault values for currents
and voltages are vital for the disturbance evaluation.
The Trip value recorder calculates the values of all selected
analog input signals connected to the Disturbance recorder
function. The result is magnitude and phase angle before and
during the fault for each analog input signal.
The trip value recorder information is available for the
disturbances locally in the IED.
ABB
The trip value recorder information is an integrated part of the
disturbance record (Comtrade file).
Disturbance recorder DRPRDRE
The Disturbance recorder function supplies fast, complete
and reliable information about disturbances in the power
M12412-6 v8
system. It facilitates understanding system behavior and
related primary and secondary equipment during and after a
disturbance. Recorded information is used for different
purposes in the short perspective (for example corrective
actions) and long perspective (for example functional
analysis).
The Disturbance recorder acquires sampled data from
selected analog- and binary signals connected to the
M12030-3 v6
Disturbance recorder function (maximum 40 analog and 128
binary signals). The binary signals available are the same as
for the event recorder function.
The function is characterized by great flexibility and is not
dependent on the operation of protection functions. It can
record disturbances not detected by protection functions. Up
to ten seconds of data before the trigger instant can be saved
in the disturbance file.
The disturbance recorder information for up to 100
disturbances are saved in the IED and the local HMI is used
to view the list of recordings.
Event function
When using a Substation Automation system with LON or
M12033-3 v8
SPA communication, time-tagged events can be sent at
change or cyclically from the IED to the station level. These
events are created from any available signal in the IED that is
connected to the Event function (EVENT). The EVENT
function block is used for LON and SPA communication.
Analog and double indication values are also transferred
through the EVENT function.
Generic communication function for Single Point indication
SPGAPC
Generic communication function for Single Point indication
SPGAPC is used to send one single logical signal to other
systems or equipment in the substation.
Measured value expander block
are provided with measurement supervision functionality. All
measured values can be supervised with four settable limits:
M12128-3 v7
low-low limit, low limit, high limit and high-high limit. The
measure value expander block has been introduced to enable
translating the integer output signal from the measuring
functions to 5 binary signals: below low-low limit, below low
limit, normal, above high limit or above high-high limit. The
output signals can be used as conditions in the configurable
logic or for alarming purpose.
