Metering; Basic Ied Functions; Human Machine Interface - ABB Relion 670 Series Product Manual

ABB
Phasor measurement unit RES670
Pre-configured
Product version: 1.2
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 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 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.
Only GPS and IRIG-B time synchronization
sources are acceptable for phasor measurement
from the accuracy point of view, and RES670
supports both.

14. Human machine interface

Human machine interface
The local human machine interface is available in
a medium sized model. Up to 12 single line
diagram pages can be defined, depending on the
product capability.
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
