IEC61850 generic communication I/O function
SPGGIO
IEC61850 generic communication I/O functions
(SPGGIO) is used to send one single logical signal
to other systems or equipment in the substation.
IEC61850 generic communication 1/O function 16
inputs
IEC 61850 generic communication I/O functions
16 inputs (SP16GGIO) function is used to send up
to 16 logical signals to other systems or
equipment in the substation.
Measurements CVMMXN, CMMXU, VNMMXU,
VMMXU, CMSQI, VMSQI
The measurement functions are used to get on-
line information from the IED. These service
values make it possible to display on-line
information on the local HMI and on the
Substation automation system about:
• measured voltages, currents, frequency,
active, reactive and apparent power and
power factor
• primary and secondary phasors
• current sequence components
• voltage sequence components
Event counter CNTGGIO
Event counter (CNTGGIO) has six counters which
are used for storing the number of times each
counter input has been activated.
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 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 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 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 (triggered).
The Indication list function shows all selected
binary input signals connected to the Disturbance
