binary inputs and outputs on the IED I/O modules (BOM,
BIM, IOM & SOM) can be forced to arbitrary values.
Central Account Management is an authentication
infrastructure that offers a secure solution for enforcing
access control to IEDs and other systems within a
substation. This incorporates management of user
accounts, roles and certificates and the distribution of
such, a procedure completely transparent to the user.
The Flexible Product Naming allows the customer to use
an IED-vendor independent 61850 model of the IED. This
customer model will be exposed in all IEC 61850
communication, but all other aspects of the IED will
remain unchanged (e.g., names on the local HMI and
names in the tools). This offers significant flexibility to
adapt the IED to the customers system and standard
solution
Description of configuration A20
The configuration of the IED is shown in
RES670 A20 configuration is applicable for a typical
single busbar single breaker arrangement monitoring up
to three bays. RES670 A20 is delivered in 1/2, 3/4 and
full (1/1)19" rack casing. For this application 12 analog
inputs are used, thus only one transformer module
(TRM) with 12 analog inputs (9I+3U) is available in A20
standard configuration. As shown in
A20 configuration as a PMU is measuring one 3-phase
voltage of the busbar and three 3-phase currents of bays
1 to 3. There are two instances of PMU reporting
functionality available in A20 configuration, meaning
two independent IEEE C37.118/1344 data streams. In the
standard A20 configuration, each instance of PMU, in
addition to frequency-deviation and rate-of-change-of-
frequency data, is reporting 16 synchrophasors over
IEEE C37.118/1344; that is four 3-phase synchrophasors
and 12 single phase synchrophasors in each data stream
corresponding to the AC voltage and current
measurements.

In addition, each data stream includes 8 analog and 8
binary reporting channels over IEEE C37.118/1344 in the
standard configuration. The number of analog and
binary reporting channels can be extended to maximum
24 channels per PMU instance (on each data stream) on
request. This can be done when ordering the RES670 A20
configuration. In the standard A20 configuration, the
analog reporting channels are used for reporting P and
Q measurements from each bay over IEEE C37.118/1344.
In addition to the binary reporting channels, there are 4
trigger bits (FREQTRIG, DFDTTRIG, OCTRIG and UVTRIG)
available per PMU instance, which are used to report the
existing protection function triggers over IEEE
C37.118/1344.
The main functionality of the RES670 is synchrophasor
reporting or PMU functionality. In addition, this
configuration also includes general back-up protection
functions which are mainly intended for alarm purposes.
Available protection functions in standard A20
configuration are Overvoltage, Undervoltage,
Overfrequency, Underfrequency and Rate-of-change
frequency.
Measuring functions for S, P, Q, I, U, PF, f are available
for local presentation on the local HMI and remote
presentation via IEEE C37.118/1344 and/or via IEC
61850. The calibration parameters on the measurement
function allows calibration at site to very high accuracy.
As shown in figure 2, there are optional functions such
as Earth fault protection (EF4 PTOC), Overcurrent
protection (OC4 PTOC), Under/Over power protection
(GUPPDUP, GOPPDOP), etc. which can be added per
request. RES670 A20 function library also includes
additional functions, which are available but not
configured. Note that RES670 A20 must be reconfigured
if any additional functions are used.
