Event counter CNTGGIO
Event counter CNTGGIO has six counters which are used for
storing the number of times each counter input has been
activated.
Event counter with limit supervison L4UFCNT
The 12 Up limit counter L4UFCNT provides a settable counter
with four independent limits where the number of positive
and/or negative flanks on the input signal are counted against
the setting values for limits. The output for each limit is activated
when the counted value reaches that limit.
Overflow indication is included for each up-counter.
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
AnRADR or BnRBDR function blocks, which are set to trigger
the disturbance recorder. All connected 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 as a reader file HDR, a configuration
file CFG, and a data file DAT. 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 recorder 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
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.
The trip value recorder information is an integrated part of the
disturbance record (Comtrade file).
