Line differential protection RED670 2.1 IEC
Product version: 2.1
Boolean 16 to Integer conversion with logic node
representation BTIGAPC
Boolean 16 to integer conversion with logic node
representation function BTIGAPC is used to transform a set of
16 binary (logical) signals into an integer. The block input will
freeze the output at the last value.
BTIGAPC can receive remote values via IEC 61850 depending
on the operator position input (PSTO).

Integer to Boolean 16 conversion IB16

Integer to boolean 16 conversion function IB16 is used to
transform an integer into a set of 16 binary (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
binary coded (logic) output signals.
ITBGAPC function can only receive remote values over IEC
61850 when the R/L (Remote/Local) push button on the front
HMI, indicates that the control mode for the operator is in
position R (Remote i.e. the LED adjacent to R is lit ), and the
corresponding signal is connected to the input PSTO ITBGAPC
function block. The input BLOCK will freeze the output at the
last received value and blocks new integer values to be received
and converted to binary coded outputs.
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.

13. 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
• measured analog values from merging units
• primary phasors
ABB
• 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.

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 DRPRDRE, 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
• Fault locator
The Disturbance report function is characterized by great
flexibility regarding configuration, starting conditions, recording
times, and large storage capacity.
A disturbance is defined as an activation of an input to the
AnRADR or BnRBDR function blocks, which are set to trigger
the disturbance recorder. All connected signals from start of
pre-fault time to the end of post-fault time will be included in the
recording.
Every disturbance report recording is saved in the IED in the
standard Comtrade format as a reader file HDR, a configuration
file CFG, and a data file DAT. The same applies to all events,
which are continuously saved in a ring-buffer. The local HMI is
used to get information about the recordings. The disturbance
report files may be uploaded to PCM600 for further analysis
using the disturbance handling tool.
