A method for controlling a genset system is provided. The method includes recognizing a communication failure between one or more gensets of a plurality of gensets and a control system and determining an operating state of each of the one or more gensets prior to the communication failure. The method further includes operating the genset system, upon communication failure, according to a load control scheme. The load control scheme includes determining an available power of the genset system based on the determined operating state of each of the one or more gensets and coupling one or more loads to the genset system based on the available power.

Method for controlling a genset system

A control system for a plurality of generator sets (gensets) includes a plurality of controllers and a data link. Each of the plurality of controllers is operatively associated with at least one of the plurality of gensets. The plurality of controllers is configured to control power output of each of the plurality of gensets, based on a plurality of operating modes. Each of the plurality of operating modes is configured for a power consumption scenario associated with the load. The datalink connects each of the plurality of controllers to at least one other controller of the plurality of controllers. The plurality of controllers is further configured to select a current operating mode, from the plurality of operating modes, for the plurality of gensets and control power output of at least one of the plurality of gensets based on the current operating mode.

An electric generator set fuel control system is disclosed. The fuel control system includes an electric generator, a prime mover mechanically coupled to the generator, a first fuel tank, a fuel level sensor configured to generate a fuel level signal indicative of a fuel level in the first fuel tank, a fuel loading operator input device configured to generate a fuel loading signal, a fueling mode operator input device configured to generate a fueling mode signal, and a control module. The first fuel tank is configured to supply fuel to the prime mover, and selectively receive or supply fuel to a second fuel tank through a fuel pump. The control module is configured to generate a fuel transfer signal as a function of the fuel loading signal, the fueling mode signal, and the fuel level signal.

Geneset fuel transfer system and method

A method of controlling a plurality of gensets during a failsafe condition is provided. The method may include operating one or more of the gensets according to a modified isochronous control scheme, and operating a remainder of the gensets according an adaptive droop control scheme. The modified isochronous control scheme may include varying the frequency of each isochronous genset with respect to load for lower-range loads and upper-range loads, and maintaining the frequency of each isochronous genset at nominal frequencies for mid-range loads. The adaptive droop control scheme may include adjusting the frequency of each droop genset to match the frequency of the isochronous gensets, and varying the load of each droop genset with respect to frequency for lower-range loads and upper-range loads.
