Xd generator vs impedance of Transformer how to calculate?

[adririza]

I work in large project, i want to ask about relationship between the Xd of generator vs impedance of transformer.
I had generator with Xd 15.3% and impedance of transformer is 30% how i can demonstrate the calculation to required the voltage drop if;

motor output rating >200kW, 50Hz,nominal 49.5-50.5 Hz max 47.5-52.5 Hz, 6.6 kV plus minus 6% during normal operation, -15% during start up. 3ph+PE

motor output rating <200kW, 50Hz, nominal 49.5-50.5 Hz max 47.5-52.5 Hz, 6.6 kV plus minus 6% during normal operation, -15% during start up. 3ph+PE

motor output rating up to 0.37kW, 50 Hz, nominal 49.5-50.5 Hz, max 47.5-52.5 Hz, 6.6 kV plus minus 6% during normal operation, -15% during start up. 1ph+PE.

need your advise
thanks in advance

Draw yourself a one-line diagram. You have a generator, a transformer and a motor. All have impedances.

Are you looking at the voltages during motor starting or running conditions?

Assign a reasonable power factor for the motor.

Look up previous threads in this forum on voltage drop and apply your values.

yes i looking for starting motor condition and running normal condition..

What magoo2 said you have to draw an one-line diagram like this attached here.

Dear Magoo2 and &znoter4 thank you for your kindness, i had try this calculation in ETAP and done for analysis.
