Question

The reactive power output of a synchronous generator is always capacitive (leading power factor), is always inductive (lagging power factor), can be both capacitive and inductive (leading and lagging power factor). A tow-pole Y-connected synchronous generator rated at 200 kVA, 480 V, 60 Hz, and 0.8 PF lagging. Its armature resistance is 0.03 ohm and synchronous reactance 0.25 ohm. The internal induced voltage of each phase at the rated conditions is 277 V 322 V 382 V A three-phase synchronous generator is connected to a 60-Hz large power system. The generator has a no-load frequency of 61.5 Hz and a slope S_P of 150 MW/Hz. The real power generated by the generator should be 225 MW 150 MW dependent on the load

Explanation / Answer

18) Reactive power of synchronous generator can be inductive or capacitive. So option C is correct option.
