  • Publication number: 20180175626
    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.

  • Publication number: 20180170685
    Abstract: A material management system and method manages and tracks the progress of excavated material transferred through an excavation site by a conveyer system operating in cooperation with an in-pit crusher and conveyer (IPCC). The material management system distinguishes the material dispensed into the IPCC into identified material batches. To track the identified material batches, the material management system records data regarding the conveyer speed and the conveyer distance associated with the IPCC, as well as possible other data regarding the identified material batches. The material management system processes this to track the indentified material batches along the conveyer route.

    Abstract: A system, method, and apparatus for controlling acceleration of a machine when the machine exits a grade. The system, method, and apparatus may determine a virtual gear having a maximum speed limit equivalent that matches the speed of the machine as the machine exits the grade. The system, method, and apparatus may also deactivate an automatic retarding control (ARC) strategy, which may be activated when the machine is on the grade to reduce and limit the speed of the machine to no more than a set speed, if the ARC strategy is active as the machine exits the grade. The system, method, and apparatus may also control automatic downshift of a transmission system to the virtual gear if the ARC mode was activing during the exit from the graded surface and is now deactive.
