Introduction
• The developments of multifunctionalintelligent electronic devices forprotection and other applications thatperform synchrophasor calculations andthe improvements in inter and intra-substation communications bring theindustry to a time when many specialists
are thinking about the use ofsynchrophasors for protectionapplications.

Synchrophasor Communications
• Increase in requirements forimprovement in the stability of electricpower systems
• IEEE 1344 Standard available since1995
• North American Synchrophasor Initiative(NASPI)
• UCTE in Europe

Phasor Measurements Concept• GPS time synchronized devices• Magnitudes and phase angles of
voltages and currents measured atdifferent locations
• Measurements sent overcommunication links
• Measurements used for differentapplications

Communications• The standard defines the formats for
frames sent out from the PMU (data,configuration, and header) and for
command frames sent to the PMU.• Mappings to serial communication and
to TCP/UDP are specified.

Data Format – Frame Content
Synchrophasors of the voltages and/orcurrents (1-phase, 3-phase, sequencecomponents)
• Frequency & frequency change• Further analog & digital values• The configuration and header frames
transmit identifiers, format specifications,and conversion factors for the valuestransmitted in the data frames.
