In a power factory, what keeps the power at a solid 60hz? It seems like turbines can't always be running at the exact same speeds, given that combustion doesn't always give the exact same temperature (my dad works at a waste to energy plant, which is why I say this).

Also, just for giggles, what would happen if AC power at a different frequency accidently got released into the lines?
