Default What 60 HZ Feels Like - Even Some On-Topic Stuff

Amazing amount of mechanical-feedback devices in use in these plants - it seems that VFDs and great many "modern" grid-tie devices are simply not sufficiently rugged or reliable at this scale.


mechanical load/speed regulators are very reliable, mechanically simple,
and do a really good job. why "improve" something that works so well?

They typically adjust the frequency setpoint on all of the generators,
which would be overseen by the ISO, and then allow the load/freq slope
to balance load between them all. i would expect that certain kinds of
generators would have a more aggressive slope than others. Nuke plants
need to keep a constant power output, but others (like hydroelectric)
can bounce all over the place as needed to manage grid power levels.

I expect that wind/solar will also try to run at 100% all of the time as
well, to keep costs down.
