Busbar protection REB650
Version 1.1 ANSI
The sequential of events logs all binary input signals
connected to the Disturbance report function. The list
may contain up to 1000 time-tagged events stored in a
FIFO-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 report function (trigged).
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
M12030-3 v4
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.
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 three seconds of data before the trigger instant can
be saved in the disturbance file.
M12033-3 v7
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.
Measured value expander block MVEXP
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 (MVGGIO) 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 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-high limit or above high limit. The
M12128-3 v6 output signals can be used as conditions in the
configurable logic or for alarming purpose.
Station battery supervision SPVNZBAT
The station battery supervision function SPVNZBAT is
used for monitoring battery terminal voltage.
SPVNZBAT activates the start and alarm outputs when the
battery terminal voltage exceeds the set upper limit or
drops below the set lower limit. A time delay for the
overvoltage and undervoltage alarms can be set according
to definite time characteristics.
