Re: Cascading Failures Could Crash the Global Internet

Yeah yeah yeah. I know that everything isn't simple. I actually worked at a power plant so none of this is new to me. Can cascading failures occur? Yes. Witness the Great Blackout in NYC. My point was that there are places where the electrical network is designed to "blow the bolts" to TRY and protect everything. Does it work? Most of the time, yes. All of the time? NO.
It is a complicated problem but you'd be suprised at how fast things can happen when you HAVE to keep the system running. There is a tremendous amount of skill concentrated in that field and they do a good job of keeping everything running well. How many turbine overspeed events do you get notified about? Those guys can do a rapid shutdown of a plant VERY quickly. Turning it back on though is a whole different matter. We needed to have one station operating so that we could actually get the big one going. Then we'd take the small one offline and bring it back up quickly to handle specific load peaks.
The loss of a single transmission line isn't going to cause a whole station to trip. If you're losing a bunch though, you've probably got lots of other problems to worry about.
