Abstract:
1. An electric power system for supplying alternating current electric power comprising: a single generator driven by an engine; a plurality of power generation sections disposed within the single generator, each power generation section including a plurality of armature windings; a plurality of inverter circuits provided one for each of the respective armature windings; an independent power generation electric wire connected to the downstream sides of the respective inverter circuits and connected to an external wire which connects an external alternating current electric power source to a consumer; means for detecting alternating current (AC) voltage in the external wire; means for detecting voltages outputted from the respective inverter circuits; means for detecting currents outputted from the respective inverter circuits; and a controller for controlling the respective inverter circuits based on the AC voltage in the external wire, the voltages in the respective inverter circuits, and the currents in the respective inverter circuits.
