Human Machine Interface; Ethernet; Time Synchronization; Local Hmi - ABB REC670 Product Manual

Bay control REC670 2.2
Product version: 2.2.1
The values of active and reactive energies are calculated from
the input power values by integrating them over a selected
time tEnergy . The integration of active and reactive energy
values will happen in both forward and reverse directions.
These energy values are available as output signals and also
as pulse outputs. Integration of energy values can be
controlled by inputs (STARTACC and STOPACC) and
setting and it can be reset to initial values with RSTACC
input.
The maximum demand for active and reactive powers are
calculated for the set time interval
are updated every minute through output channels. The
active and reactive maximum power demand values are
calculated for both forward and reverse direction and these
values can be reset with RSTDMD input.

• Graphical display capable of showing a user defined single
line diagram and provide an interface for controlling
switchgear.
• Navigation buttons and five user defined command buttons
to shortcuts in the HMI tree or simple commands.
• 15 user defined three-color LEDs.
• Communication port for PCM600.
The LHMI is used for setting, monitoring and controlling.

17. Basic IED functions

Time synchronization

The time synchronization function is used to select a common
source of absolute time for the synchronization of the IED
when it is a part of a control and a protection system. This
makes it possible to compare events and disturbance data
between all IEDs within a station automation system and in
between sub-stations. A common source shall be used for
IED and merging unit when IEC/UCA 61850-9-2LE process
bus communication is used.
Precision time protocol PTP
PTP according to IEEE 1588-2008 and specifically its profile
IEC/IEEE 61850-9-3 for power utility automation is a
synchronization method that can be used to maintain a
common time within a station. This time can be synchronized
to the global time using, for instance, a GPS receiver. If PTP
is enabled on the IEDs and the switches that connect the
station are compatible with IEEE 1588, the station will
become synchronized to one common time with an accuracy
of under 1us. Using an IED as a boundary clock between
several networks will keep 1us accuracy on three levels or
when using an HSR, 15 IEDs can be connected in a ring
without losing a single microsecond in accuracy.

18. Ethernet

Access points
An access point is an Ethernet communication interface for
single or redundant station communication. Each access
point is allocated with one physical Ethernet port, two
physical Ethernet ports are allocated if redundant
communication is activated for the access point.
