Abstract
A power system architecture includes a prime mover, a plurality of single phase permanent magnet generators mechanically coupled to the prime mover, a DC power bus including a plurality of DC power storage components, each of the DC energy storage components being electrically connected to at least one of the single phase permanent magnet generators, a plurality of state of charge calculators, each of the state of charge calculators being connected to one of the DC energy storage component and being communicatively coupled to a generator control unit, and wherein the generator control unit is configured to independently control each of the single phase permanent magnet generators.
Claims17
A power system architecture comprising:
- a prime mover;
- a plurality of single phase permanent magnet generators mechanically coupled to the prime mover, each of said single phase permanent magnet generators includes a control winding configured to at least partially control an output voltage of the single phase permanent magnet generator;
- a DC power bus including a plurality of DC energy storage components, each of the DC energy storage components being electrically connected to at least one of the single phase permanent magnet generators;
- a plurality of state of charge calculators, each of the state of charge calculators being connected to one of the DC energy storage component and being communicatively coupled to a generator control unit;
- and
- wherein said generator control unit is configured to independently control each of said single phase permanent magnet generators by independently controlling a current through each of said control windings.
A method for re-balancing energy storage devices within a DC power generating system comprising:
- identifying at least one energy storage device in a plurality of energy storage device as having a reduced charge relative to a remainder of energy storage devices;
- and
- increasing a control current to a single phase permanent magnet generator corresponding to the identified at least one energy storage device, wherein the single phase permanent magnet generator is one of a plurality of single phase permanent magnet generators, and wherein the plurality of single phase permanent magnet generators includes at least one unique single phase permanent magnet generator corresponding to each energy storage device in the plurality of energy storage devices.
