This problem tells you that a wye-wye transmission line is stepped down from 230KV to 200KV using three auto xfmrs connected line to neutral. For each phase, the auto Xfmr is rated 500 MVA, and the turns ratio is 5:2 (common:series). Then it asks to find Apparent Power in common coil. The...
This is a problem on finding the Maximum Power Output for a question generator. They use a formula
P=3*Vphase*Vinternal / Xsynchronous
I'm a little confused as to Why the solutions use this problem. Can anyone explain?
Thanks!
