This was not the generator speeding up beyond its tolerances. From what I understood from this article, it sped up slightly (still safely within its tolerances), but the difference in frequency made it out-of-phase with the power grid. Once it was connected, the misaligned electromagnetic field instantly tried to align the shaft (and match its rotation speed); that's where the sudden torque came from.
