Monitoring - ABB Relion 650 series RET650 Product Manual

ABB
Transformer protection RET650
Product version: 1.1
• GATE function block is used for whether
or not a signal should be able to pass from
the input to the output.
• XOR function block.
• LOOPDELAY function block used to delay
the output signal one execution cycle.
• TIMERSET function has pick-up and drop-
out delayed outputs related to the input
signal. The timer has a settable time delay.
• AND function block.
• SRMEMORY function block is a flip-flop
that can set or reset an output from two
inputs respectively. Each block has two
outputs where one is inverted. The memory
setting controls if the block should be reset
or return to the state before the
interruption, after a power interruption. Set
input has priority.
• RSMEMORY function block is a flip-flop
that can reset or set an output from two
inputs respectively. Each block has two
outputs where one is inverted. The memory
setting controls if the block should be reset
or return to the state before the
interruption, after a power interruption.
Reset input has priority.

B16I
Boolean 16 to integer conversion function
(B16I) is used to transform a set of 16 binary
(logical) signals into an integer.
Boolean 16 to Integer conversion
with logic node representation
B16IFCVI
Boolean 16 to integer conversion with logic
node representation function (B16IFCVI) is
used to transform a set of 16 binary (logical)
signals into an integer.

Integer to Boolean 16 conversion
IB16A
Integer to boolean 16 conversion function
(IB16A) is used to transform an integer into a
set of 16 binary (logical) signals.
Integer to Boolean 16 conversion
with logic node representation
IB16FCVB
Integer to boolean conversion with logic
node representation function (IB16FCVB) is
used to transform an integer to 16 binary
(logic) signals.
IB16FCVB function can receive remote values
over IEC61850 depending on the operator
position input (PSTO).

11. Monitoring

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.
