It's been my experience that faults generally cause disconnect in about 2-4 seconds. For some reason the safety failed to disconnect the section where the fault was from the grid. Yes, but shouldn't there be more trigger/switches/whatever to have stopped this from being hit buy so many areas? .. They all seemed to have failed till it hit Valley Forge

The situation went on for too long and the grid destabilized. When that happens the power plant have to drop off to protect their generators. (They can be seriously damaged)
The generator has to have a stable frequency on the grid or they will fight it and destroy themselves, not to mention all the related equipment.

Exactly. That sure points to some major problems in the system.
