2023-12-06 05:05:01 <KipIngram   > You know, I'd never thought about how difficult it might be to bring the grid back online after a widesprerad power outage.  I assume they have some ability to disconnect sections of the grid, but it's probably not incredibly fine-grained.  You have no idea when you start to fire up the power how many switches out there are on and how many are off.
2023-12-06 05:05:42 <KipIngram   > All those big rotating machines are intended to be running continuously.  Trying to start them all up at once would be "interesting," to say the least, and starting just one might expose it to more load than it could service.
2023-12-06 05:05:48 <KipIngram   > So I bet it's quite a juggle.
2023-12-06 05:06:12 <KipIngram   > Obviously they know how to do it, but I figure it takes more planning that I'd ever thought about.
2023-12-06 05:16:14 <KipIngram   > ah, I see.  A subset of the power stations in a grid are 'black start' plants.  They can turn themselves on using backup power sources.  And they can then power up other plants in the network.  And yeah - they can disconnect the cities and towns and stuff from the transmission line networks needed for that.
2023-12-06 05:16:38 <KipIngram   > So they switch everyone out, fire up the black start paths, fire up the other plants, and then brings the loads back into the network.
2023-12-06 05:16:44 <KipIngram   > black start plants
2023-12-06 05:17:56 <KipIngram   > Hydroelectric plants are often used for black starts, because they don't have to spin up their generator rotors - the water will do that.  They only need a small amount of electricity to run their monitoring and control equipment during startup.
2023-12-06 05:20:08 <KipIngram   > Another thing most people don't think about is that all of the generators connected in parallel in a section of the grid have to be phase matched.  It wouldn't do for them to try to drive out-of-phase voltages onto the grid.  Once they're all running they are controlled to stay in phase, but that's another thing that's tricky during a full startup.
2023-12-06 05:24:42 <KipIngram   > Wow - initial load on a system when it's first brought back online can be 8-10 times its normal average.  Every air conditioner, every refrigerator, every water heater, etc. - they all want to run at the same time.  And every induction motor out there will start drawing its inrush current.
2023-12-06 05:24:55 <KipIngram   > It can be half an hour before the demand starts to come back down toward normal.

2023-12-06 14:44:48 <KipIngram   > Yeah, I can make sense of it (as a title).  I can imagine someone being lured to Forth because it's so simple and easy to learn but then later becoming jaded to it simply because it expects you to do more or less all of your coding yourself - you just don't find "libraries" like in C, Python, etc.
2023-12-06 14:45:15 <KipIngram   > I use Python quite a lot, and it's precisely because that huge availability of packages usually makes it easy to "quickly get something done."
2023-12-06 14:45:57 <KipIngram   > My own attraction to Forth, though, has nothing to do with what I can do with it.  I just love the language itself.
