Monitoring - ABB Relion 670 Series Product Manual

ABB
Phasor measurement unit RES670
Pre-configured
Product version: 1.2
• PULSETIMER function block can be used, for
example, for pulse extensions or limiting of
operation of outputs, settable pulse time.
• 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's output should reset or return to the
state it was, 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's output should reset or return to the
state it was, after a power interruption. RESET
input has priority.
Fixed signal function block
The Fixed signals function (FXDSIGN) generates a
number of pre-set (fixed) signals that can be used
in the configuration of an IED, either for forcing
the unused inputs in other function blocks to a
certain level/value, or for creating certain logic.

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
• positive, negative and zero sequence
currents and voltages
• mA, input currents
• pulse counters
Supervision of mA input signals
The main purpose of the function is to measure
and process signals from different measuring
transducers. Many devices used in process
control represent various parameters such as
frequency, temperature and DC battery voltage as
low current values, usually in the range 4-20 mA
or 0-20 mA.
Alarm limits can be set and used as triggers, e.g.
to generate trip or alarm signals.
The function requires that the IED is equipped
with the mA input module.
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 , 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
