Human Machine Interface - ABB Relion 670 Series Product Manual

Busbar protection REB670
Customized
Product version: 1.2
The function is characterized by great flexibility and is not
dependent on the operation of protection functions. It can
record disturbances not detected by protection functions. Up
to ten seconds of data 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 LON and SPA communication.
Analog and double indication values are also transferred
through EVENT function.
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
signal 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 be used as conditions in the
configurable logic or for alarming purpose.
13. 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.
22
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.
14. 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.

15. Human machine interface

Human machine interface
The local HMI is equipped with a LCD that is used among
other things to locally display the following crucial information:
• Connection of each bay, respecting the two differential
protection zones and the check zone. In the Parameter
Setting Tool the user sets individual bay names to
facilitate the identification of each primary bay for station
personnel.
• Status of each individual primary switchgear device, for
example, open, closed, 00 as intermediate state and 11
as bad state. In PCM600 the user sets the individual
primary switchgear object names to facilitate the
identification of each switchgear device for the station
personnel.
The local HMI is divided into zones with different functionality.
• Status indication LEDs.
• Alarm indication LEDs, which consist of 15 LEDs (6 red
and 9 yellow) with user printable label. All LEDs are
configurable from PCM600.
• Liquid crystal display (LCD).
• Keypad with push buttons for control and navigation
purposes, switch for selection between local and remote
control and reset.
• Isolated RJ45 communication port.
