    Abstract: An alternator includes an exciter field device generating an exciter magnetic field in a first air gap, an exciter armature device configured to rotate with respect to the exciter magnetic field and impart a first voltage in a first set of coils at the first air gap, a main stator device including a second set of coils, and a rotor field device configured to be energized by the first current in the first set of coils and generate a main magnetic field that imparts a second voltage on the main stator device at a second air gap. The main stator device and the exciter field device lie in on a common plane normal to an axis of rotation, and the exciter armature device is inwardly spaced from the exciter field device, main stator device, and the rotor field device.

    Abstract: In one embodiment, a generator includes a rotor configured to rotate in cooperation with a stator to generate electrical power. An exciter of the generator includes at least one circuit board, a stationary exciter stator, and a control circuit. The circuit board is mechanically coupled to a rotor of the generator and includes at least one coil of an electrical conductor. The stationary exciter stator is configured to induce a current in the at least one coil of the at least one circuit board. The control circuit is configured to modify the current from the at least one coil and provide the modified current to a field of the generator.

    Abstract: Some embodiments relate to a method of adding and shedding loads that are connected to a generator. The method includes determining whether a plurality of loads is being supplied with power by the generator and then determining the total load that the generator is supplying to the plurality of loads. The method further includes determining whether to change a number of the loads in the plurality of loads based on the amount of load L that is being supplied by the generator. The method further includes determining an amount of time T in which to change the number of loads in the plurality of loads based on the amount of load that is being supplied by the generator.

    Abstract: A generator system includes a generator controller for monitoring the operation of generator cable. The generator controller is configured to receive a first signal indicative of a generator output and a first connection of a generator cable and a second signal indicative of a second connection of the generator cable. The generator controller is configured to calculate a characteristic value for the generator cable based on the first signal and the second signal and compare the characteristic value for the generator cable to a threshold value. A generator status message or a generator command is generated in response to the comparison. The characteristic value may be resistance of the generator cable.

    Abstract: A generator system may include redundant control. The generator system may include any combination of redundant controllers, redundant communication paths, or other redundant control. A generator system may include an electrical bus, a first generator controller, and the second generator controller. The first generator controller may control a first generator breaker for connecting a first generator to the electrical bus and configured to control an external breaker for selectively connecting the electrical bus to an external source. The second generator controller may control a second generator breaker for connecting a second generator to the common bus and configured to control the external breaker for selectively connecting the electrical bus to the external source.

    Abstract: A generator or another type machine includes a controlled field alternator, a segmented waveform converter, and a controller. The controlled field alternator is configured to generate a polyphase signal. The segmented waveform converter includes multiple switches connected between the polyphase signal of the controlled field alternator and an output filter. The controller is configured to provide a control signal for the switches based on measured electrical quantities associated with the output filter and provide a field current control signal to the controlled field alternator.

    Abstract: A generator system may include two or more generators electrically connected through a generator bus. A controller receives operation data from a first generator. The operation data may describe a power flow from a second generator to the first generator. From the operation data, either a loss of speed control or a loss of voltage control may be identified at the second generator. The controller may generate a command for the second generator based on the loss of speed control or the loss of voltage control.
