摘要： 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.

摘要： A hydraulic fracturing system includes an engine, transmission, and 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 an advisory system including a display, a memory storing fuel consumption data and component durability data, and a controller. The controller is programmed to receive pump flow and pressure settings, identify an optimal transmission gear based on the pump flow and pressure settings, the fuel consumption data and the component durability data, and cause the optimal transmission gear to be displayed on the display.

摘要： 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.

摘要： A system for detecting an abnormal operating condition of a component of a genset power system, which includes an engine drivingly coupled to a generator, is provided. The system also includes at least one vibration sensor configured to measure vibrations of the genset power system, and a controller. The controller is programmed to receive vibration sensor data from the vibration sensor, and process the vibration sensor data using a modeling software to generate simulated data. The simulated data is filtered using frequency-based filtering to obtain filtered data, and frequency domain information of the filtered data is compared to threshold data to identify the abnormal operating condition of the component.

摘要： A rig management system is disclosed. The rig management system may be configured to receive information to be used to control shifting of a transmission to prevent cavitation during use of the hydraulic fracturing rig. The rig management system may be configured to determine a flow rate for a pump based on the information. The rig management system may be configured to determine an output torque of the transmission based on the flow rate. The rig management system may be configured to determine a transmission gear for the transmission based on the output torque and a fuel consumption map, wherein the fuel consumption map identifies a respective fuel consumption rate for different combinations of transmission gears and output torques. The rig management system may be configured to cause the transmission to shift into the transmission gear after determining the transmission gear.
