b) Based on the results it can be concluded that with 16% impedance of GSU transformer, Generator

can operate at its rated 0.85 lagging power factor for a grid voltage variation from 95% to 103%. For a

grid voltage variation of 104% to 105%, MVAR delivered by Generator shall be reduced to maintain

the generator terminal voltage within its specified limits.

c) During leading power factor, for grid voltage variation from 102% to 105%, MVAR absorbed by the

Generator has to be reduced to maintain the generator terminal voltage within its specified limits.
