Abstract: Systems and methods for increasing the efficiency of inverters are provided. In some embodiments, an inverter may be configured to connect to a direct current power source and output alternating current power. The inverter may include one or more transistors configured to receive a direct current signal and output a pulse width modulated signal having a particular switching frequency or spread spectrum frequencies. The inverter also includes a low pass filter having multiple elements where each of the multiple elements have parasitic characteristics. One or more of the multiple elements may be designed such that the frequency response has a notch or a minimum at the switching frequency while having a desired cutoff frequency.

Abstract: A genset enclosure includes a skid platform, a plurality of gusset members, a plurality of roof supports, and a first and second plurality of sidewall panels. The gusset members are spaced along an outer perimeter of the skid platform and are coupled to the skid platform using fasteners. The gusset members are arranged in opposed pairs positioned on opposite lateral ends of the skid platform. Each gusset member defines a first portion extending upwardly from the skid platform normal to an upper surface of the skid platform and a second portion disposed at an upper end of the first portion and extending normal to the first portion and toward a centerline of the skid platform. The gusset members support the plurality of roof supports and the first and second plurality of sidewall panels to form an enclosed volume.

Abstract: A method for controlling a dual fuel engine system includes determining a friction power loss amount of an internal combustion engine of the dual fuel engine system, where the friction power loss amount is based on an engine speed of the internal combustion engine and a friction torque estimate. The method also includes determining an accessory power loss amount of a power of the internal combustion engine, where the accessory power loss amount is based on the engine speed and an accessory torque estimate. The method further includes estimating a net engine power amount based on the accessory power loss amount and a brake power amount of the internal combustion engine, estimating an indicated diesel power, and estimating, based on the estimated net engine power, a first indicated engine power and a first gas power.

Abstract: A method for controlling a dual fuel engine system includes determining a gas flow target for an internal combustion engine of the dual fuel engine system, where the gas flow target is based on a gas power target of the internal combustion engine, a thermal efficiency estimate of the internal combustion engine, and a lower heating value (LHV) within the internal combustion engine. The method also includes adjusting the gas flow target based on at least one of a measured gas temperature or a measured gas injector pressure and determining at least one base gas injector command based on the adjusted gas flow target, a gas substitution rate estimate, and a gas substitution rate target. The method further includes determining, based on the at least one base gas injector command, a gas injector command for at least one engine bank.

Abstract: Systems and methods for managing loads on a power grid are provided. In some embodiments, the load control system includes one or more power sources connected to a power grid. A method includes determining, by a first genset connected to a power grid, a power average at a first rate, and generating, by the first genset, a filtered power average. The filtered average includes the power average at a second rate. The filtered power average is used in a second algorithm to balance the load share of power sources on the power grid.
