What’s the difference between asynchronous and synchronous generators?

Question

An easy-to-understand answer,please.

Answer 1

If a generator without a commutator is used to supply power to an AC power grid, its rotation must be precisely timed to match the frequency and phase of the grid. If not, it will either distort the waveform on the grid, draw power from the grid instead of supplying it, or simply be destroyed. Its motion must be synchronized to the grid.

Answer 2

"Synchronous" refers to doing something st the same time, as if you were to say to 5-6 people: "Okay, synchronize your watches". That would mean everyone sets their watch at exactly the same time. Or take another example: people synchronize fireworks ! Meaning they all go off at the same time, (more or less), with slight variations to make the Macy's show more interesting. "Asynchronous" means the opposite: everything goes off/on whenever, they are not "set" at the same time. Think of the "Synchronized women's swimming team", they all "dance" underwater so beautifully, why? Because it is synchronized, they all do the same movements, at the same time. If the dances were to be asynchronized, well...imagine what it would look like! Everyone splashing around in all directions, lol.
Now, how this applies to generators, I suppose it's like this: if power were to go out in a hospital, they would synchronize all generators to start at the same time, so people that are getting surgery, giving labor, receiving treatment, etc. won't die without necessary electricity. Hope I helped!
