Hi
If you go back into the Frequency Control Symposium papers from the
1980's there are several of them from the power line people on using GPS
to
track 60 Hz. They have kept at it ever
My Tymeter just clacked over to 50 minutes after, and I had a sudden vision of
GPS locking its input to 60 Hz, like in the good old days when the power
companies cared about frequency. =) Has anyone actually gone that far in
their time-madness?

there are several of them from the power line people on using GPS to track 60
Hz. They have kept at it ever since. Their main interest is in tracking phase
across a large network, rather than locking up generators
and a good clock.

Hi
If you go back
The guys who put up the original papers were from Quebec Hydro. Their issue
was trying to set things up independent of the grid and dispatch power to
where ever it was needed. Once they demonstrated it was possible a lot of
other people became interested. Oddly enough at dinner I brought up
measurement

Hi
Apparently if you are generating hydro station type levels and sending it out
over long distance lines, the EMI is pretty fierce. They tried various LF and
HF solutions and could not get a good enough signal to be useful.
