A method and system of power generating is provided to reduce a startup time of a genset for providing requested power to a utility grid or a load. The genset includes a generator, a turbocharger, and an energy storage. The generator includes an engine. The genset responds to a genset start signal by accelerating an engine speed of the generator to reach a synchronous speed. The engine speed is accelerated more rapidly by activating the energy storage device to supply power to at least one of the generator and the turbocharger. The generator then supplies power to the utility grid or load.

Method and system for reducing a startup time of a genset

The present disclosure provides an engine fueling system that includes multiple fueling valves such that the fuel transport delay can be reduced. The fueling system may also include an electrically driven compressor to improve engine properties during engine startup. For example, an engine fueling system comprising: a first compressor; an intake air throttle operably coupled to the first compressor and positioned downstream of the first compressor; a primary fuel path in communication with a fuel supply, wherein a first fuel from the fuel supply is injected into the primary fuel path upstream from the compressor; and a secondary fuel path in communication with the fuel supply, wherein a second fuel from the fuel supply is injected into the secondary fuel path downstream from the compressor.

Two point fuel system for gas power generation

A spark-ignited gas engine system comprises a combustion chamber defined by a piston, a head with a spark plug mechanism, and a cylinder having an associated intake valve and an associated exhaust valve, into which a mixture of combustible gas and air is entered via an intake manifold of the engine to drive a crankshaft. The system further comprises at least one turbocharger to compress the mixture. The system further comprises at least one camshaft, driven by the crankshaft via a gear assembly connected to the crankshaft, that comprises at least one cam that actuates the intake valve and the exhaust valve, at least one camphaser, coupled to the crankshaft via the gear assembly, and a controller to adjust a cam angle operation of the intake valve and the exhaust valve by adjusting the camphaser to a desired phase position to meet a target rotational phase of the camshaft.
