What is Regulation Calculation for 50 kVA Alternator about?

An alternator has a rated load of 50 kVA at 550V. With a field current of 10A, its open circuit voltage is 300V and short circuit current is 150A. The armature resistance is 0.15 ohms and effective resistance is 1.5 times the ohmic resistance. The question asks to determine the regulation of the alternator operating at 0.8 power factor lagging.
