A 3000KVA, 6600V, 60Hz wye-connected synchronous generator hassynchronous reactance of 11.3ohms per phase and armature resistanceof zero, that is, armature resistance may be ignored.
A) Calculate the excitation voltage line-to-line when the generator is operating at rated voltage and rated current at apower factor of 0.9 lagging.
B) Calculate the full load voltage regulation.
C) If the load is changed to pure resistance and the generatoris still operating a rated current and rated voltage calculate thenew output power and new armature current.
D) Under these new conditions, should the filed current beincreased or decreased?
