Introduction

There are two different software alternatives with which the IED can be ordered. The intention is that
these configurations shall suit most applications with minor or no changes. The few changes required on
binary input and outputs can be done from the signal matrix tool in the PCM600 engineering platform.
Only the main PMU reporting function (first instance) is switched Enabled at delivery. The other PMU
reporting function (second instance) and all the protection functions are switched Disabled at delivery.
Back-up functions that are not generally used are also set to Disabled.
The configurations are:
• A20 – Phasor Measurement Unit, 3 bays, single busbar, 12AI (9I+3U)
• B20 – Phasor Measurement Unit, 6 bays, double busbar, 24AI (9I+3U , 9I+3U)
All IEDs can be reconfigured with the help of the Application Configuration Tool (ACT) in the PCM600
engineering platform. The IED can be adapted to special applications and special logic can be
developed.
On request, ABB is available to support the re-configuration work, either directly or to do the design
checking.
Optional functions and optional IO ordered, will not be configured at delivery. It means that the user shall
configure and add them to the standard configuration. It should be noted that the standard only includes
one binary input and one binary output module and only the important outputs such as protection function
alarms are connected to the outputs. The required total IO must be calculated and specified at ordering.
Hardware modules are configured with the hardware configuration tool in the PCM600 engineering
platform.

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
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
