Every power generator tied to the national power grid must be synchronized (in phase) with the AC frequency. There is an interesting procedure of how generators black start from a total power blackout. This is interesting and complex when one considers that the power grid is supplied by numerous massive mechanical generators in coal-fired plants, natural gas, nuclear, and hydroelectric generators.
The AC power grid is a remarkably stable frequency source for maintaining time-of-day clocks etc. This is accomplished by counting and registering the total number of AC cycles generated over a 24-hour period. The generator rotational speed is adjusted to bring the total cycle count to a predetermined value.
There must be a master generator on the grid that does this frequency regulation. Where is this master generator?
