摘要： A system and method for operating a fleet of pumps for a turbine driven fracturing pump system used in hydraulic fracturing is disclosed. In an embodiment, a method of operating a fleet of pumps associated with a hydraulic fracturing system includes receiving a demand Hydraulic Horse Power (HHP) signal. The demand HHP signal may include the Horse Power (HP) required for the hydraulic fracturing system to operate and may include consideration for frictional and other losses. The method further includes operating all available pump units at a percentage of rating below Maximum Continuous Power (MCP) level, based at least in part on the demand HHP signal. Furthermore, the method may include receiving a signal for loss of power from one or more pump units. The method further includes operating one or more units at MCP level and operating one or more units at Maximum Intermittent Power (MIP) level to meet the demand HHP signal.

摘要： A system and method of enhancing operation of hydraulic fracturing equipment at a hydraulic fracturing wellsite may include determining if a hydraulic fracturing stage profiles are available for use for hydraulic fracturing equipment at a wellsite. The method may include prompting an acceptance or amendment of one of the hydraulic fracturing stage profiles for a hydraulic fracturing pumping stage. The method may include, in response to an amendment of one of the hydraulic fracturing stage profiles, prompting acceptance of the amended hydraulic fracturing stage profile as the current hydraulic fracturing stage profile for use in association with the controller. The method may include, when a hydraulic fracturing stage profile is not available, prompting configuration of hydraulic fracturing pumping stage parameters for the current hydraulic fracturing stage profile. The method may include storing the current hydraulic fracturing stage profile as the previous hydraulic fracturing stage profile in association with the controller.

摘要： Systems and methods for operating hydraulic fracturing units, each including a hydraulic fracturing pump to pump fracturing fluid into a wellhead and an internal combustion engine to drive the hydraulic fracturing pump, may include receiving signals indicative of operational parameters. The systems and methods also may include determining an amount of required fracturing power sufficient to perform the hydraulic fracturing operation, determining an available power to perform the hydraulic fracturing operation and a difference between the available power and the required power, and controlling operation of the hydraulic fracturing units based at least in part on the power difference. When the power difference is indicative of excess power available, the system and methods may include causing at least one of the hydraulic fracturing units to idle, and when the power difference is indicative of a power deficit, increasing a power output of at least one of the hydraulic fracturing units.

摘要： A methods and system to operate hydraulic fracturing units may include utilizing hydraulic fracturing unit profiles. The system may include hydraulic fracturing units may include various components. The components may include an engine and associated local controller and sensors, a transmission connected to the engine, transmission sensors, and a pump connected to the transmission and powered by the engine via the transmission and associated local controller and sensors. A supervisory controller may control the hydraulic fracturing units. The supervisory controller may be in communication with components of each hydraulic fracturing unit. The supervisory controller may include instructions to, for each hydraulic fracturing units, obtain hydraulic fracturing unit parameters, determine a hydraulic fracturing unit health assessment, and build a hydraulic unit profile including the health assessment and parameters. The supervisory controller may, based on the health assessment, determine the hydraulic fracturing unit's capability to be operated at a maximum power output.

摘要： Systems and methods to increase intake air flow to a gas turbine engine of a hydraulic fracturing unit when positioned in an enclosure may include providing an intake expansion assembly to enhance intake air flow to the gas turbine engine. The intake expansion assembly may include an intake expansion wall defining a plurality of intake ports positioned to supply intake air to the gas turbine engine. The intake expansion assembly also may include one or more actuators connected to a main housing of the enclosure and the intake expansion assembly. The one or more actuators may be positioned to cause the intake expansion wall to move relative to the main housing between a first position preventing air flow through the plurality of intake ports and a second position providing air flow through the plurality of intake ports to an interior of the enclosure.
