Andy, it appears to me that the FNET/GridEye system already does what you propose: http://fnetpublic.utk.edu
The Angle Contour Map displays the kind of results you desire. But it doesn't know the Western Interconnection at this time. I believe there is a typo at the top of the Angle Contour Map: > The frequency gradient map visualizes the real-time angle "differences" with > respect to a referential point in Eastern > Interconnection. Shouldn't that state: "The ANGLE CONTOUR MAP visualizes ..."? According to the legend, the angle contour map displays a measure of the phase angle differences between the individual FDR hosts and a "referential point". I'm not sure if that is an actual specific FDR host or some averaged phase. Of course, you need to think carefully in a relativistic manner when you are trying to look at local phase in locations so far apart. At 60 Hz (in the US) 1 degree of phase corresponds to 46.3 us. That's the free space propagation delay of light over 13.89 km (8.63 miles). Generators 777 miles apart have a 90 degree phase relationship with respect to free space propagation phase. -- Bill Byrom N5BB Irving, TX On Mon, Jul 8, 2019, at 6:11 AM, Andy Backus wrote: > To clarify: > > My research proposal is for data to be taken within the same interconnection. > > It does not care about frequency. > > It does not care about Time Error. > > It only seeks to characterize the phase differences between the power > line signal presented in regions of the distribution system separated > by significant geographical distances. > > 180-degree phase reversals and three-phase transformations along the > chain of information are easily distinguishable. > > Thanks for your interest.
