Line distance protection REL670 2.2
Product version: 2.2
copied to SI_OUT output. The time part of single position
input is copied to TIME output. The quality bits in the
common part and the indication part of inputs signal are
copied to the corresponding quality output.
• INVALIDQT function which sets quality invalid of outputs
according to a "valid" input. Inputs are copied to outputs. If
input VALID is 0, or if its quality invalid bit is set, all outputs
invalid quality bit will be set to invalid. The time stamp of an
output will be set to the latest time stamp of INPUT and
VALID inputs.
• INVERTERQT function block that inverts the input signal
and propagates the time stamp and the quality of the input
signal.
• ORQT OR function block that also propagates the time
stamp and the quality of the input signals. Each block has
six inputs and two outputs where one is inverted.
• PULSETIMERQT Pulse timer function block can be used,
for example, for pulse extensions or limiting of operation of
outputs. The function also propagates the time stamp and
the quality of the input signal.
• RSMEMORYQT 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 after a power interruption
should return to the state before the interruption, or be
reset. The function also propagates the time stamp and
the quality of the input signal.
• SRMEMORYQT 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 after a power interruption
should return to the state before the interruption, or be
reset. The function also propagates the time stamp and
the quality of the input signal.
• TIMERSETQT function has pick-up and drop-out delayed
outputs related to the input signal. The timer has a settable
time delay. The function also propagates the time stamp
and the quality of the input signal.
• XORQT XOR function block. The function also propagates
the time stamp and the quality of the input signals. Each
block has two outputs where one is inverted.
Extension logic package
The logic extension block package includes additional trip
matrix logic and configurable logic blocks.
Fixed signal function block FXDSIGN
The Fixed signals function (FXDSIGN) has nine 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
ABB
level/value, or for creating certain logic. Boolean, integer,
floating point, string types of signals are available.
One FXDSIGN function block is included in all IEDs.
Elapsed time integrator with limit transgression and overflow
supervision TEIGAPC
The Elapsed time integrator function (TEIGAPC) is a function
that accumulates the elapsed time when a given binary signal
has been high.
The main features of TEIGAPC
• Applicable to long time integration (≤999 999.9 seconds).
• Supervision of limit transgression conditions and overflow.
• Possibility to define a warning or alarm with the resolution
of 10 milliseconds.
• Retaining of the integration value.
• Possibilities for blocking and reset.
• Reporting of the integrated time.
Boolean to integer conversion, 16 bit B16I
Boolean to integer conversion, 16 bit (B16I) is used to transform
a set of 16 boolean (logical) signals into an integer.
Boolean to integer conversion with logical node
representation, 16 bit BTIGAPC
Boolean to integer conversion with logical node representation,
16 bit (BTIGAPC) is used to transform a set of 16 boolean
(logical) signals into an integer. The block input will freeze the
output at the last value.
Integer to Boolean 16 conversion IB16
Integer to boolean 16 conversion function (IB16) is used to
transform an integer into a set of 16 boolean (logical) signals.
Integer to Boolean 16 conversion with logic node
representation ITBGAPC
Integer to boolean conversion with logic node representation
function (ITBGAPC) is used to transform an integer which is
transmitted over IEC 61850 and received by the function to 16
boolean (logic) output signals.
Comparator for integer inputs INTCOMP
The function gives the possibility to monitor the level of integer
values in the system relative to each other or to a fixed value. It
is a basic arithmetic function that can be used for monitoring,
supervision, interlocking and other logics.
Comparator for real inputs REALCOMP
The function gives the possibility to monitor the level of real
value signals in the system relative to each other or to a fixed
value. It is a basic arithmetic function that can be used for
monitoring, supervision, interlocking and other logics.
