Human Machine Interface - ABB RET670 Product Manual

Transformer protection RET670 ANSI

Product version: 1.2
before the trigger instant can be saved in the
disturbance file.
The disturbance recorder information for up to 100
disturbances are saved in the IED and the local HMI
is used to view the list of recordings.
Event function
When using a Substation Automation system with
LON or SPA communication, time-tagged events
can be sent at change or cyclically from the IED to
the station level. These events are created from any
available signal in the IED that is connected to the
Event function (EVENT). The event function block is
used for remote communication.
Analog and double indication values are also
transferred through EVENT function.
IEC61850 generic communication I/O function
SPGGIO
IEC61850 generic communication I/O functions
(SPGGIO) is used to send one single logical signal
to other systems or equipment in the substation.
IEC61850 generic communication I/O functions
MVGGIO
IEC61850 generic communication I/O functions
(MVGGIO) function is used to send the
instantaneous value of an analog output to other
systems or equipment in the substation. It can also
be used inside the same IED, to attach a RANGE
aspect to an analog value and to permit
measurement supervision on that value.
Measured value expander block RANGE_XP
The current and voltage measurements functions
(CVMMXN, CMMXU, VMMXU and VNMMXU),
current and voltage sequence measurement
functions (CMSQI and VMSQI) and IEC 61850
generic communication I/O functions (MVGGIO) are
provided with measurement supervision
functionality. All measured values can be supervised
with four settable limits: low-low limit, low limit, high
limit and high-high limit. The measure value
expander block (RANGE_XP) has been introduced
to enable translating the integer output signal from
the measuring functions to 5 binary signals: below
low-low limit, below low limit, normal, above high-
high limit or above high limit. The output signals can
22
be used as conditions in the configurable logic or
for alarming purpose.
12. Metering
Pulse counter logic PCGGIO
Pulse counter (PCGGIO) function counts externally
generated binary pulses, for instance pulses coming
from an external energy meter, for calculation of
energy consumption values. The pulses are
captured by the binary input module and then read
by the function. A scaled service value is available
over the station bus. The special Binary input
module with enhanced pulse counting capabilities
must be ordered to achieve this functionality.
Function for energy calculation and demand
handling ETPMMTR
Outputs from the Measurements (CVMMXN)
function can be used to calculate energy
consumption. Active as well as reactive values are
calculated in import and export direction. Values
can be read or generated as pulses. Maximum
demand power values are also calculated by the
function.
13. Basic IED functions
Time synchronization
The time synchronization source selector is used to
select a common source of absolute time for the
IED when it is a part of a protection system. This
makes it possible to compare event and
disturbance data between all IEDs in a station
automation system.

Human machine interface
The local HMI is divided into zones with different
functionality.
