Nominal Voltage UN= 3000v (Y)

Line frequency f=50 Hz

Number of ole pairs= 2

Synchronous Reactance X1= 2.5 ohms

There is no reactive power and the generator can be assumed as lossless.

Please calculate Load angel and pole wheel voltage Up

Formula and my solution,

I=PN/UN

I=3MVA/3000V

I=1000A

UN=XI +Up

Up= 3000v-2.5*1000A

UP=500v which is wrong

Load angel ? I don't know
