Q19. A 3-phase, 420 V, 60 Hz, Y-connected synchronous generator, with a synchronous reactance of 1.20 Ohm per phase is connected to an infinite bus. The power angle, when supplying 110 kW to the bus is 30 degree. What will be the total apparent power (in kVA) injected by this generator to infinite bus?
