A three-phase, 410-kVA, 2300-V alternator has an armature resistance of 0.4 ohm per phase and a synchronous reactance of 1.3 ohm per phase. Determine the no-load line-to-line generated voltage and the voltage regulation at 1) Full-load kVA, 0.82 power factor lagging, and rated voltage. 2) Full-load kVA, 0.73 power factor leading, and rated voltage. 3) Explain why the generator voltage regulation is different for different load power factors.
