The Disturbance report function is characterized by
great flexibility regarding configuration, initiating
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 FIFO-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.
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 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
(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
