[Gllug] re; synching generators to the grid

[t.clarke]

About 20 years ago I took a tour round the Dinorwig (if thats how you spell it)
pumped-storage power-station in deepest Wales.   I vaguely recollect the guy
saying that it detected the need for extra power on the grid by checking
the grid frequency - if it dropped more than a certain number of points the
sluice gates opened and the water-turbine whizzed up to speed and on load within
about 30 seconds.  Of course my memory may be totally faulty !

I never did ask him how they managed to synch up the turbine generators to the
grid.  For that matter, how do they do it with wind power ?
