Answer Posted / ramdarkmaster
In case of D.C generator it is supplying only active power(Kw) because the no capacitance or inductance loads connected to D.C generator, it's purely resistive. but in case of alternator it supplying inductive as well as capacitative load hence there are both active power(Kw) and reactive power(Kvar) and both combined together real power(KVA), hence alternator ratings are in KVA's.
