    It trips me out that many of these plants don’t have APUs for starting themselves up, or that they were designed in such a way that they require utility power to boot up. Like I understand that black starts could have problems with frequency sync with no point of reference, but I can’t imagine that their control system circuits don’t have any form of self-powering redundancy built in to their design. Is there any reason for this?

      We didn’t have digital controls when they were designed, so you couldn’t use GPS or atomic clocks to synchronize frequencies, you just needed to have a single source of coordination. Those coils were manually controlled till not long ago.

      Now we should be able to use some kind of small gas turbine with a igbt rig for synchronization, much like they do with wind turbines.

      People often don’t appreciate how far we’ve come over the past 2 decades, and how utterly manual and brute force we were until very, very recently.
