I have some doubts about the X Source in Generator Model, is it Xd' or some thing else ?

The Xsource in the generator power flow model is the unsaturated subtransient reactance in p.u. Please refer to PAGV1.pdf for more information about the generator model.

Thanks for replying. Why it is in steady state generator tab ?

In PSS/E, the power flow model is linked with the dynamic model. The PSS/E checks for the value of Xsource in the power flow to see if it is the same as the X" in the generator dynamic model.

It's also used in short circuit calculations.

The unsaturated subtransient reactance cannot be used for short-circuit calculations.

How else would the generator impedance be modelled for short circuit contribution?
