Abstract: An output of a generator may vary according to the speed of the engine, physical characteristics of the engine, or other factors. A profile for a generator that describes a periodic fluctuation in an operating characteristic for the generator is identified. A field current of an alternator associated with the generator is modified based on the profile for the generator in order to counter variations in the output of the generator.

Abstract: A method of determining an operation of at least one of a plurality of generators in a power generation system. The method includes identifying a system parameter that is related to operation of the power generation system; and determining which of the plurality of generators to operate to minimize fuel consumption of the power generation system based on the system parameter. Other methods include identifying a system parameter that is related to operation of the power generation system; and determining which of the plurality of generators to operate by optimizing an operating variable of the power generation system based on the system parameter.

Abstract: A set of generators are connected in parallel using a generator bus. At least one of the generators is associated with a controller. The controller detects an overload condition on the generator bus caused by a load and disconnects an initial generator from the generator bus in response to the overload condition. The initial generator continues to run during the overload condition after disconnecting from the generator bus but alternator excitation may be removed from the initial generator. The controller initiates starting one or more additional generator without alternator excitation. The controller also initiates connecting the initial generator and the one or more additional generators to the generator bus connected to the load. Alternator excitation is applied to the initial generator and the one or more additional generator so that adequate power may be applied to the load.

Abstract: Some embodiments relate to an internal combustion engine that includes a combustion chamber and a rotating component. The internal combustion engine further includes a sensing system that detects an angular position of the rotating component. A controller calculates a ratio between air and fuel in the combustion chamber based on the detected position of the rotating component. As an example, the rotating component may be a crankshaft where the controller calculates a speed of the crankshaft and an acceleration of the crankshaft based on the detected position of the crankshaft.

Abstract: Some embodiments relate to a controlled field alternator where the alternator is wired in a low wye configuration (coils wired in series or parallel). The first sensor measures the direct current flowing through the field within the alternator to detect an excitation level of a field within the alternator. As examples, the first sensor may measure field voltage, magnetic field intensity, magnetic flux density, current to the field of a rotating exciter, voltage to the field of a rotating exciter and the duty cycle of a pulse width modulated signal that controls an on-board rectifier for a permanent magnet exciter. Embodiments are also contemplated where the second sensor measures the RMS output voltage of the alternator to determine the output characteristic of the alternator.
