Abstract: A system for detecting wear or failure of a genset coupling of a genset power system is provided. The system includes a vibration sensor for measuring vibrations, and an additional sensor for measuring an operating condition. A controller is configured to process operating condition data from the additional sensor using a modeling software to generate simulated data. The controller applies time domain information of at least one of the simulated data and vibration sensor data to the modeling software using a machine learning algorithm, and perform a comparison to identify wear or failure of the coupling, wherein, when performing the comparison, the controller compares at least one of: time domain information of the vibration sensor data to time domain information of the simulated data or frequency domain information of the vibration sensor data to frequency domain information of the simulated data, to identify wear or failure of the coupling.

Abstract: A system for monitoring a pump, while the pump operates at a worksite, is disclosed. The system includes one or more sensors, wherein each of the one or more sensors is associated with the pump and is configured to collect high frequency data associated with the pump. The system further includes a field-programmable gate array (FPGA) controller configured to receive the high frequency data from the one or more sensors and is also configured to generate low frequency data based on the high frequency data. The system further includes a low frequency controller configured to receive the low frequency data from the FPGA controller and configured to transmit the low frequency data to a monitor.

Abstract: A hydraulic fracturing system comprises a plurality of hydraulic fracturing rigs. Each hydraulic fracturing rig includes an engine, a transmission, and a hydraulic fracturing pump. A driveshaft is coupled between the transmission and the hydraulic fracturing pump to transfer torque from the engine to the hydraulic fracturing pump. The hydraulic fracturing system also includes a fuel consumption data for each hydraulic fracturing rig, and a controller. The controller is programmed to receive a total pump flow and pressure request, and identify a pump flow distribution for each hydraulic fracturing rig of the plurality of hydraulic fracturing rigs based on the total pump flow and pressure request and the fuel consumption data.
