Abstract

See full text

A generator system configured to be connected in parallel with other generators is disclosed. The generator system includes an alternator having a stator with an output winding and a quadrature winding and a rotor with a three-phase winding. The rotor of the alternator is rotatably driven by an engine having a controller to regulate the engine speed. An inverter receives power from the quadrature winding and generates an AC voltage for the rotor winding. The inverter receives an input corresponding to the voltage on the output winding of the stator and also receives an input corresponding to the phase angle of a second AC voltage produced by another power source. The inverter controls the frequency of the AC voltage for the rotor winding such that the phase angle of the voltage on the output winding of the stator is synchronized to the phase angle of the second AC voltage.
