  • Publication number: 20240151126
    Abstract: A control system identifies preferred performance information associated with a hydraulic fracturing system; and obtains engine operation information associated with a plurality of engines included in a plurality of respective pump systems of the hydraulic fracturing system. The control system identifies, based on the engine operation information, a set of one or more engines, of the plurality of engines, that are utilizing gaseous fuel and/or that are capable of utilizing gaseous fuel, and obtains methane number information associated with the set of one or more engines. The control system selects, based on the preferred performance information and the methane number information, a set of one or more operation optimization maps, determines, based on the set of one or more operation optimization maps and the engine operation information, control information associated with the plurality of pump systems. The control system controls, based on the control information, the plurality of pump systems.

  • Patent number: 10243371
    Abstract: A control system, apparatus, and method to control load sharing of multiple generator sets of a power supply system are described. Load transient set points to add an individual generator set can include a transient percentage threshold to characterize load transients as a load transient, a transient count threshold, and a transient count time period during which a detected number of load transients is compared with the transient count threshold. A controller can determine whether to add the individual generator set based on whether the detected number of load transients is equal to the transient count threshold within the transient count time period and control addition of the individual generator set responsive to the detected number of load transients equaling the transient count threshold.
