Explicitly limit discussion to electrical machines, and expand the description of how synchronous machines work.

| Mar 16 at 14:54 | comment | added | t-osu | thank you this has always confused me so much about direct grid connected generators. When you say "apply grid power to it, and apply torque to its shaft" the torque is coming from the flow of water? so the role of controlling the flow of water is not controlling the output frequency but rather controlling the rotors speed to be faster than the synchronous speed? and then for a synchronous hydroturbine generator...the output frequency is determined by the flow of water, and the voltage by the strength of the DC excitation? | |
