Logic; Monitoring - ABB RES670 Product Manual

Phasor measurement unit RES670 ANSI
Customized
Product version: 1.2
bring in commands from REMOTE (SCADA) to those parts of
the logic configuration that do not need extensive command
receiving functionality (for example, SCSWI). In this way, simple
commands can be sent directly to the IED outputs, without
confirmation. Confirmation (status) of the result of the
commands is supposed to be achieved by other means, such
as binary inputs and SPGGIO function blocks. The commands
can be pulsed or steady.
AutomationBits, command function for DNP3.0 AUTOBITS
AutomationBits function for DNP3 (AUTOBITS) is used within
PCM600 to get into the configuration of the commands coming
through the DNP3 protocol. The AUTOBITS function plays the
same role as functions GOOSEBINRCV (for IEC 61850) and
MULTICMDRCV (for LON).
Single command, 16 signals
The IEDs can receive commands either from a substation
automation system or from the local HMI. The command
function block has outputs that can be used, for example, to
control high voltage apparatuses or for other user defined
functionality.

10. Logic

Tripping logic SMPPTRC (94)
A function block for protection tripping is provided for each
circuit breaker involved in the tripping of the fault. It provides a
settable pulse prolongation to ensure a trip pulse of sufficient
length, as well as all functionality necessary for correct co-
operation with autoreclosing functions.
The trip function block also includes a settable latch
functionality for evolving faults and breaker lock-out.
Trip matrix logic TMAGGIO
Trip matrix logic TMAGGIO function is used to route trip signals
and other logical output signals to different output contacts on
the IED.
TMAGGIO output signals and the physical outputs allows the
user to adapt the signals to the physical tripping outputs
according to the specific application needs.
Configurable logic blocks
A number of logic blocks and timers are available for the user to
adapt the configuration to the specific application needs.
• OR function block.
• INVERTER function blocks that inverts the input signal.
12
• 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.
• 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.

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
• positive, negative and zero sequence currents and voltages
• mA, input currents
• pulse counters
