A 3 Phase, 50 Hz Synchronous generator is connected to an infinite bus through a transformer and two parallel transmission lines. The input mechanical power to synchronous generator is 0.8 p.u. Grid is consuming a power of 0.8 + j0.4 p.u. Generator impedance is 0.25 p.u., transformer impedance is 0.5 p.u. and each transmission line impedance is 0.5 p.u. If the infinite bus voltage is 1∠0 p.u then, what is the generator voltage load angle?
