Alternator for a power generation system

摘要

The present invention relates to an alternator (11) for a power generation system, the alternator comprising a stator (12) that includes a main output winding (13), a poly-phrase auxiliary winding (14), and an exciter field winding (not shown) powered by the poly-phase auxiliary winding, wherein the poly-phase auxiliary winding is magnetically decoupled from the main output winding, a rotor that includes an exciter secondary winding and a rotary field winding powered by the exciter secondary winding; and a regulator that measures a current to the exciter field winding and controls the current to a set point in order to regulate an output voltage produced by the main output winding of the stator.
