A synchronous generator is running over excited with Ef = 1.4 p.u. This machine a synchronous reactance of 1.2 pu, is delivering a synchronous power of .5 p.u to the bus. If prime-mover torque is increased by 1%, then change in reactive power is
1
1% increase
2
1% decrease
3
0.475 % increase
4
0.475 % decrease
5
None of these
