Sequential of events DRPRDRE
Continuous event-logging is useful for monitoring
the system from an overview perspective and is a
complement to specific disturbance recorder
functions.
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 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 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 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 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
