The function requires that the IED is equipped with the mA
input module.
Event counter CNTGGIO
Event counter (CNTGGIO) has six counters which are used for
storing the number of times each counter input has been
activated.
Disturbance report DRPRDRE
Complete and reliable information about disturbances in the
primary and/or in the secondary system together with
continuous event-logging is accomplished by the disturbance
report functionality.
Disturbance report DRPRDRE, always included in the IED,
acquires sampled data of all selected analog input and binary
signals connected to the function block with a, maximum of
40 analog and 96 binary signals.
The Disturbance report functionality is a common name for
several functions:
• Event list
• Indications
• Event recorder
• Trip value recorder
• Disturbance recorder
The Disturbance report function is characterized by great
flexibility regarding configuration, starting conditions,
recording times, and large storage capacity.
A disturbance is defined as an activation of an input to the
AxRADR or BxRBDR function blocks, which are set to trigger
the disturbance recorder. All signals from start of pre-fault
time to the end of post-fault time will be included in the
recording.
Every disturbance report recording is saved in the IED in the
standard Comtrade format. The same applies to all events,
which are continuously saved in a ring-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 report function. The list may contain up to 1000
time-tagged events stored in a ring-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
ABB
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 report function (triggered).
The Indication list function shows all selected binary input
signals connected to the Disturbance report 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 report 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 report
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.
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
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
Disturbance report function (maximum 40 analog and 96
binary signals). The binary signals available are the same as
for the event recorder function.
