Question-3 [30 Points] (a) A wye-connected generator has a nameplate rating of 200 MVA, 20 kV, and its subtransient reactance (X) is 1.2 pu. Determine its reactance in ohms. (b) The generator is now connected to a power system where the base is specified as 100 MVA, 13.8 kV. What is the generator reactance in per unit on this system base? (c) Convert the per-unit answer calculated in part (b) to ohms. Does this match the value determined in part a?
