Alpha=20.5 deg
Current to infinte bus=1+j0.181 pu
Voltage behind transient reactance= E'= 0.892+j0.6 pu = 1.075 @33.9 deg pu
Maximum power that can be transferred under the following condition is
(a)System Healthy:
Pmax=1.79 pu
Pe=1.79 sin(delta) pu
(b)One line shorted in the middle:
Pmax=0.6933 pu
Pe=0.6933 sin(delta) pu
(c)One line open :
Pmax=1.2643 pu
Pe=1.2643 sin(delta) pu
