How many phasor measurements (voltage amplitude and phase angle) does a typical PMU capture from 1) transmission and 2) distribution lines? is it one, three, or more? Does this depend on the topology of transmission/distribution grid, and how do they differ?

I would appreciate it if you could explain in details.

  • \$\begingroup\$ I haven't asked them yet. Do all transmission and distribution lines have three phasors? can it be less or more? \$\endgroup\$

The PMU samples power at the nominal frequency of 50 or 60 Hz and reports on current and voltage at a typical rate of 48 samples-per-cycle with one micro-second accuracy. The output of the PMU is a stream of time-tagged synchrophasors at a rate of up to 60 samples-per-second. https://www.safaribooksonline.com/library/view/smart-grid-communication-enabled/9781118820247/OEBPS/9781118820247_epub_c_13.htm
