Abstract: An apparatus for predicting a load event in a generator system or a method for predicting the load event in the generator system may include monitoring output data associated with an electrical output of a generator, monitoring external sensor data associated with the generator, detecting a load event for the generator from the output data, identifying a subset of the external sensor data that preceded the load event from the output data, performing an analysis of the subset of the external sensor data, and determining a load event characteristic from the analysis, the load event characteristic indicative of a subsequent load event for the generator.

Abstract: A generator waveform is measured using one or more techniques that reduce the computing resources for measuring the generator waveform and the time required for measuring the generator waveform. One example includes a template matching technique that iteratively selects templates to estimate the phase offset of the generator waveform. One example includes a root mean squared value calculated from less than sample time period that is less than one half of a cycle of the generator waveform. A generator controller calculates a command or parameter for the generator based on the estimated phase offset or the root mean squared value.

Abstract: A dual compressor turbocharger includes two compressors. One compressor supplies fuel pressure, and one compressor supplies air pressure. The dual compressor turbocharger includes a turbine driven by exhaust of an engine and a shaft coupled to the turbine. The first compressor is mounted on the shaft and includes a first inlet coupled to an air supply and a first outlet coupled to an air intake of the engine. The second compressor is mounted on the shaft and includes a second inlet coupled to a fuel supply and a second outlet coupled to a fuel supply rail of the engine.

Abstract: A generator system includes at least one generator, at least one generator controller, and a power bus. The power bus transmits power to a load circuit. Data communications are also transmitted by the power bus. In one example, multiple generator controllers exchange messages over the power bus. In another example, one or more generator controllers exchange messages with a central controller over the power bus. The messages may include a status for the generators, output values for the generators, or commands for the generators.

Abstract: An apparatus includes a controlled field alternator or utility source of electrical power, a conversion device, and a controller. The conversion device includes a first power input associated with a first power source, a second power input associated with a second power source, and circuitry configured to perform a first conversion of power from a first format from the first power source to a second format for charging the second power source and perform a second conversion of power from the second format for the second power source to a third format for supplying a load.

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 fuel delivery system may be utilized in an internal combustion engine or a generator engine. The fuel delivery system includes a fuel injector and a venturi. The venturi provides a force for delivering the fuel into the manifold of the engine, and the fuel injector provides metering to control the amount of fuel delivered into the manifold of the engine. In one example, the fuel delivery system includes a first chamber configured to enclose a gaseous fuel, a second chamber configured to direct a flow of air through the venturi, and a plunger. The plunger is controlled to selectively connect and disconnect the first chamber and the second chamber to control the flow of the gaseous fuel into the second chamber under a differential pressure of the venturi.

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.
