Control; Logic - ABB Relion 670 Series Product Manual

Phasor measurement unit RES670
Pre-configured
Product version: 1.2
A criterion based on delta current and delta
voltage measurements can be added to the fuse
failure supervision function in order to detect a
three phase fuse failure, which in practice is more
associated with voltage transformer switching
during station operations.

9. Control

Logic rotating switch for function selection and
LHMI presentation SLGGIO
The logic rotating switch for function selection
and LHMI presentation function (SLGGIO) (or the
selector switch function block) is used to get a
selector switch functionality similar to the one
provided by a hardware selector switch.
Hardware selector switches are used extensively
by utilities, in order to have different functions
operating on pre-set values. Hardware switches
are however sources for maintenance issues,
lower system reliability and an extended purchase
portfolio. The logic selector switches eliminate all
these problems.
Selector mini switch VSGGIO
The Selector mini switch VSGGIO function block
is a multipurpose function used for a variety of
applications, as a general purpose switch.
VSGGIO can be controlled from the menu or from
a symbol on the single line diagram (SLD) on the
local HMI.
IEC 61850 generic communication I/O functions
DPGGIO
The IEC 61850 generic communication I/O
functions (DPGGIO) function block is used to
send double indications to other systems or
equipment in the substation. It is especially used
in the interlocking and reservation station-wide
logics.
Single point generic control 8 signals SPC8GGIO
The Single point generic control 8 signals
(SPC8GGIO) function block is a collection of 8
single point commands, designed to 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
14
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
A function block for protection tripping is
provided for each circuit breaker involved in the
tripping of the fault. It provides 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 includes 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.
