Trip Value Recorder Drprdre; Disturbance Recorder Drprdre; Event Function; Measured Value Expander Block Range_Xp - ABB REC670 Product Manual

Bay control REC670 2.2
Product version: 2.2.1
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.
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 recorder function (maximum 40 analog and 352
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
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, integer and double indication values are also
transferred through the EVENT function.
Generic communication function for Single Point indication
SPGAPC
ABB
Generic communication function for Single Point indication
(SPGAPC) is used to send one single logical signal to other
systems or equipment in the substation.
M12128-3 v7
Generic communication function for measured values
MVGAPC
Generic communication function for measured values
(MVGAPC) function is used to send the instantaneous value
of an analog signal to other systems or equipment in the
substation. It can also be used inside the same IED, to attach
a RANGE aspect to an analog value and to permit
measurement supervision on that value.

Measured value expander block RANGE_XP

The current and voltage measurements functions (CVMMXN,
CMMXU, VMMXU and VNMMXU), current and voltage
sequence measurement functions (CMSQI and VMSQI) and
IEC 61850 generic communication I/O functions (MVGAPC)
M12156-3 v11
are provided with measurement supervision functionality. All
measured values can be supervised with four settable limits:
low-low limit, low limit, high limit and high-high limit. The
measure value expander block (RANGE_XP) 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.
Insulation supervision for gas medium function SSIMG
Insulation supervision for gas medium (SSIMG) is used for
monitoring the circuit breaker condition. Binary information
based on the gas pressure in the circuit breaker is used as
input signals to the function. In addition, the function
generates alarms based on received information.
Insulation supervision for liquid medium SSIML
Insulation supervision for liquid medium (SSIML) is used for
monitoring the transformer condition. Binary information
based on the oil level in the transformer is used as input
signals to the function. In addition, the function generates
alarms based on received information.
Circuit breaker condition monitoring SSCBR
M12805-6 v11 The circuit breaker condition monitoring function (SSCBR) is
used to monitor different parameters of the breaker condition.
The breaker requires maintenance when the number of
operations reaches a predefined value. For a proper
functioning of the circuit breaker, it is essential to monitor the
circuit breaker operation, spring charge indication or breaker
wear, travel time, number of operation cycles and estimate
the accumulated energy during arcing periods.
Fault locator LMBRFLO
The accurate fault locator is an essential component to
minimize the outages after a persistent fault and/or to pin-
point a weak spot on the line.
