Settings for Synchrophasors
PMSTN and PMID
Defines the name and number of the PMU. The PMSTN setting is an ASCII
string with as many as 16 characters. The PMID setting is a numeric value.
Use your utility or synchrophasor data concentrator naming convention to
determine these settings.
PHDATAV, VXCOMP,
VYCOMP, and VSCOMP
PHDATAV selects which voltage synchrophasors to include in the data packet.
Consider the burden on your synchrophasor processor and offline storage
requirements when deciding how much data to transmit. This setting is one of
seven settings that determine the minimum port SPEED necessary to support
the synchrophasor data packet rate and size—see Communications Bandwidth
on page H.16 for detailed information.

PHDATAV := V1 transmits only positive-sequence voltage, V

➤
PHDATAV := NA does not transmit any voltages
Table H.2 describes the order of synchrophasors inside the data packet.
The VXCOMP, VYCOMP, and VSCOMP settings allow correction for any
steady-state voltage phase errors (from the potential transformers or wiring
characteristics). See Synchrophasor Measurement on page H.2 for details on
this setting.
PHVOLT
PHVOLT selects which voltage side (X or Y or both) to include in the data
packet. Consider the burden on your synchrophasor processor and offline
storage requirements when deciding how much data to transmit. This setting is
one of the seven settings that determine the minimum port SPEED necessary
to support the synchrophasor data packet rate and size - see Communications
Bandwidth on page H.16 for detailed information.
PHDATAI, IXCOMP, and
IYCOMP
PHDATAI selects which current synchrophasors to include in the data packet.
Consider the burden on your synchrophasor processor and offline storage
requirements when deciding how much data to transmit. This setting is one of
the seven settings that determine the minimum port SPEED necessary to
support the synchrophasor data packet rate and size—see Communications
Bandwidth on page H.16 for detailed information.

The IXCOMP and IYCOMP settings allow correction for any steady-state
phase errors (from the current transformers or wiring characteristics). See
Synchrophasor Measurement on page H.2 for details on these settings.
Table H.2 describes the order of synchrophasors inside the data packet.
Synchrophasors are transmitted in the order indicated from the top to the
bottom of the table. Real values are transmitted first and imaginary values are
transmitted second.
Synchrophasors are only transmitted if specified to be included by the
PHDATAV and PHDATAI settings. For example, if PHDATAV := ALL and
PHDATAI := I1, selected phase voltages are transmitted first (See PHVOLT
setting), followed by VS input voltage, positive-sequence voltage, and
positive-sequence current.
