The rating of each generator at the Three Gorges Dam(TGD) in China is quoted as 778 MVA of apparent power (see ?38.2.3) produced at 20 kV and 50 Hz. Given that the quoted real power is 700 MW, what power factor has been assumed? The TGD generator rotors turn at 75 rpm. Assuming a three-phase stator winding, as in Figure 38.9

, what is the pole structure of the rotors? What is the current in the stator windings?
