Abstract: A stored energy power source uses a wound-rotor induction machine (WRIM) to receive energy from an external source, store the energy in N energy storage elements (ESEs) via tertiary windings, and discharge the ESEs to deliver energy via a secondary winding to a load producing output. Each discharging ESE contributes to a total flux at the secondary winding to sum the individual ESEs voltages. These voltages can be stepped up or down by a transformation ratio between the secondary winding and each of the tertiary windings. A flywheel may be coupled to the secondary to store and delivery energy. Load factor power control can be used to stabilize the output voltage. The source may be configured to allow for the bi-directional flow of energy between an external power source, the ESEs, the flywheel and the load. The WRIM provides a safe, reliable and efficient system to provide high-level AC and DC output voltages.

Abstract: An example system includes a dynamo-electric machine. The dynamo-electric machine includes a rotor that is cylindrical and that is configured for rotation and a stator that is arranged relative to the rotor. The stator has a stepped configuration that defines a first diameter for the stator and a second diameter for the stator. The first diameter is greater than the second diameter. Zones of the stator at the first diameter hold direct-axis (D-axis) windings and zones of the stator at the second diameter hold quadrature axis (Q-axis) windings. An airgap between the rotor and the Q-axis windings is greater than an airgap between the rotor and the D-axis windings.

Abstract: A system includes a power distribution bus configured to distribute power from an electrical power source. The system also includes a plurality of electrical loads configured to receive portions of the power from the electrical power source. The system further includes a doubly-fed induction machine (DFIM) configured to reduce transmission impedance on the power distribution bus in response to a change in real or reactive power at one or more of the electrical loads, and reduce low frequency power oscillations at the source.

Abstract: A stored energy power source uses a wound-rotor induction machine (WRIM) to receive energy from a prime mover via a rotating shaft, provide magnetization reactive energy from a self-excited AC capacitor bank, store the energy in N energy storage elements (ESEs) via tertiary windings, and discharge the ESEs to deliver energy via a secondary winding to a load producing output. Each discharging ESE contributes to a total flux at the secondary winding to sum the individual ESEs voltages. These voltages can be stepped up or down by a transformation ratio between the secondary winding and each of the tertiary windings. A flywheel may be coupled to the shaft to store and delivery kinetic energy. Load factor power control can be used to stabilize the output voltage. The source may be configured to allow for the bi-directional flow of energy between the ESEs, the flywheel and the load. The WRIM provides a safe, reliable and efficient system to provide high-level AC and DC output voltages.
