Configuration
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, V, 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
Overcurrent protection (OC4PTOC), 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.
