Power source system controlling a plurality of generators

摘要

In the case where the rotation speeds of respective magneto alternating current (AC) generators of a plurality of power source apparatuses (10, 20, and 30) are approximately the same rotation speed and the total electric power generation demand is the same as or smaller than the maximum total generated electric power of the plurality of power source apparatuses (10, 20, and 30), the integrated control unit (6) for integrally controlling the plurality of power source apparatuses (10, 20, and 30) selects at least one of the plurality of the power source apparatuses (10, 20, and 30) and controls a voltage control unit (5) of the selected power source apparatus in such a way that the selected power source apparatus generates maximum generated electric power thereof, at the rotation speed, that is the same as or smaller than the total electric power generation demand.

1. A power source system provided with a plurality of power source apparatuses and an integrated control unit that can integrally control the plurality of power source apparatuses in accordance with a total electric power generation demand:
wherein each of the power source apparatuses is provided with a magneto alternating current (AC) generator provided with a rotor having magnetic poles for producing magnetic field flux and an armature winding that generates an AC current based on rotation of the rotor; a rectification unit that rectifies an AC current generated by the magneto alternating current (AC) generator into a DC current; a DC voltage transformer that receives electric power based on a DC output voltage of the rectification unit and transforms the DC output voltage of the rectification unit into an inter-input-terminal voltage of an electric load; and a voltage control unit that controls the transformation ratio of the DC voltage transformer, based on at least an operation status signal indicating the operation status of the magneto alternating current (AC) generator, wherein in the case where the rotation speeds of the respective magneto alternating current (AC) generators of the plurality of power source apparatuses are approximately the same rotation speed and the total electric power generation demand is smaller than the maximum total generated electric power of the plurality of power source apparatuses, the integrated control unit selects at least one of the plurality of the power source apparatuses and controls the voltage control unit of the at least one selected power source apparatus in such a way that the at least one selected power source apparatus generates maximum generated electric power thereof, at the rotation speed, that is the same as or smaller than the total electric power generation demand, and wherein at least another of said power source apparatuses is operated at a transformation ratio different from that of said at least one power source apparatus, to meet the power generation demand.
