A system and method for providing constant-frequency electrical power from variable-speed mechanical power are disclosed. The system includes a wound-rotor induction machine generator (WRIMG), a first power converter, e.g., an inverter or a bridge rectifier, that provides power from the stator assembly of the WRIMG to the load, and a second power converter, e.g., an inverter or a bridge rectifier, that provides power from the rotor assembly of the WRIMG to the load. A controller controls the output stator-current based on comparisons between measured DC load bus data and a reference DC load bus voltage value, measured machine shaft angular position and reference rotor frequency data, and measured stator-current data that is fed-back to the stator-current controller by the power converter device(s).

What I claim is: 1. A system for providing constant-frequency, electrical output from a variable-speed mechanical input, the system comprising: at least one mechanical-to-electrical energy converter, each of said at least one mechanical-to-electrical energy converter including: a first wound-rotor
What I claim is: 1. A system for providing constant-frequency, electrical output from a variable-speed mechanical input, the system comprising: at least one mechanical-to-electrical energy converter, each of said at least one mechanical-to-electrical energy converter including: a first wound-rotor induction machine having a rotor assembly and a stator assembly, the rotor assembly including a plurality of rotor windings for inducing a stator current in a plurality of stator windings disposed on the stator assembly, the rotor assembly being mechanically-coupled to a shaft driven by a mechanical power delivering device; a first power converter having an input electrically-coupled to said stator windings and an output electrically-coupled to a first DC load bus; a second power converter having an input electrically-coupled to said rotor windings and an output electrically-coupled to a second DC load bus; and a controller operative to control at least one of said first and second power converters to regulate the DC load bus voltage on the associated DC load bus, wherein the controller includes a plurality of comparators and said controller is operative, using said plurality of comparators to compare stator-current magnitude data, stator-current phase data, and measured stator-current data to reference data, to control at least one of the first and the second power converters. 2. The system as recited in claim 1, wherein the mechanical power delivering device is selected from the group comprising a diesel generator, a wind turbine, a flywheel energy storage supply device, a gas-powered motor, and a hydro-powered turbine. 3. The system as recited in claim 1, wherein the first power converter and the second power converter are each selected from the group comprising an AC-DC inverter and a rectifier bridge. 4. The system as recited in claim 1, wherein the first DC load bus and the second DC load bus are the same load bus. 5. The system as recited in claim 1, wherein the system further comprises at least one DC-AC inverter having an input electrically-coupled to each of the first and second DC load buses. 6. The system as recited in claim 5, wherein the first and the second DC load buses are the same bus and said at least one DC-AC inverter is a single inverter. 7. The system as recited in claim 5, wherein said at least one DC-AC inverter comprises first and second DC-AC inverters and said first DC-AC inverter having an input electrically-coupled to the first DC load bus and said second DC-AC inverter having an input electrically-coupled to the second DC load bus. 8. The system as recited in claim 1, wherein at least one of the wound-rotor induction machine generators is operative to convert electrical power from the DC load bus into kinetic energy for storage in a flywheel energy storage system. 9. The system as recited in claim 8, wherein, the controller of said at least one mechanical-to-electrical energy converter is operative to cause the flywheel energy storage system to deliver mechanical energy to the rotor assembly of the first wound-rotor induction machine when electrical power from the DC load bus is no longer being converted into kinetic energy. 10. The system as recited in claim 1, wherein the controller is operative to obtain stator-current magnitude data, stator-current phase data, and measured stator-current data and, utilizing said data, to control at least one of the first and the second power converters. 11. The system as recited in claim 1, wherein the controller is operative, using a voltage measured from the first or second DC load bus and a reference DC load bus voltage, to determine stator-current magnitude data to adjust torque levels of the wound-rotor induction machine generator. 12. The system as recited in claim 1, wherein controller is operative to use a torque reference value of the wound-rotor induction machine generator to determine stator-current magnitude reference data to adjust torque levels of the wound-rotor induction machine generator.
