Phasor Aliases in Data Configuration q
Phasor Name, Alias
This is a freeform setting category with two arguments. Specify the phasor name
and an optional 16-character alias to be included in the synchrophasor data
stream q. See Table 10.17 on page 10.30 and Table 10.18 on page 10.30 for a list
of phasor names that the PMU supports. The PMU can be configured for as many
as 20 unique phasors for each PMU configuration.
Synchrophasor Analog Quantities in Data Configuration q (Maximum 16 Analog
Quantities)
Analog Quantity Name or Alias
This is a freeform setting category with one argument. Specify the analog quan-
tity name or its alias to be included in the synchrophasor data stream q. See
Section 12: Analog Quantities for a list of analog quantities that the PMU sup-
ports. The PMU can be configured for as many as 16 unique analog quantities for
each data configuration q. The analog quantities are floating point values, so each
analog quantity the PMU includes will take four bytes.
Synchrophasor Digitals in Data Configuration q (Maximum 64 Digitals)
Relay Word Bit Name or Alias.
This is a freeform setting category with one argument. Specify the Relay Word
bit name or its alias that you need to include in the synchrophasor data stream q.
See Section 11: Relay Word Bits for a list of Relay Word bits that the PMU sup-
ports. You can configure the PMU for as many as 64 unique digitals for each data
configuration q.
