Article issues[edit]

I chose to edit the history section as it needs better context of why these devices are important in today’s power systems and potential uses for distribution systems as well. The article simply just mentions how the device was invented. The operation section needed to be updated with information about the new operating techniques of PMUs and uPMUs for distribution systems. Additionally some statements about how they currently operate are incorrect. Lastly, the applications section also needed to be appended and more detailed to include applications uPMUs.

This page is written like an advertisement promoting a technology. It has a positive bias with speculation. More importantly, it doesn't reveal what synchrophasors actually are. (What a mathematical construct like phasors has to do with synchronized timing measurements eludes me. I don't think many other people will do better.) OTOH, a web search reveals many references, so it seems to be notable. Saligron 13:04, 2 February 2007 (UTC)

Others cleaned out the commercial nonsense. I have added some bridge concepts so that the relationship is clearer, also links to applications in power systems. I deliberately used non technical language on the intro and image so that folks can get a surface understanding without the need to dive into the math details. -J JMesserly (talk) 00:55, 1 December 2008 (UTC)

Requested move[edit]

Phasor measurement unit (PMU) is by far the more common term for a synchrophasor. -J JMesserly (talk) 00:56, 1 December 2008 (UTC)

PMU VS SynchroPhasor Definitions for Clarification[edit]

SynchroPhasor is defined by IEEE C37.118-2005 Standard for Synchrophasors for Power Systems, IEEE Power Engineering Society, as:
"A phasor calculated from data samples using a standard time signal as a reference for the measurement. Synchronized phasors from remote sites have a defined common phase relatinship."

Phasor Measurement Unit (PMU) is defined by the NASPI PSTT PMU Definition task group May 22, 2008 as:
"A device that provides as a minimum synchrophasor and frequency measurements for one or more three phase AC voltage and/or current waveforms. The synchrophasors can be single phase or symmetrical component values. The synchrophasor and frequency values must meet the general definition and minimum accuracy required in the IEEE Synchrophasor Standard, C37.118-2005."
