Abstract: In some implementations, a controller may obtain a setting for a maximum discharge pressure associated with a fluid pump that is to be allowed during a hydraulic fracturing operation. The fluid pump may be driven by a motor that is controlled by a variable frequency drive (VFD). The controller may determine a maximum torque for the motor that achieves the maximum discharge pressure. The controller may cause, via the VFD, adjustment to a speed of the motor to maintain a torque of the motor at or below the maximum torque for the motor.

Abstract: In some implementations, a controller may monitor, in connection with a fluid pump driven by a motor that is controlled by a variable frequency drive and over a time period, a torque of the motor to obtain torque data, a speed of the motor to obtain speed data, and a pressure of the fluid pump to obtain pressure data. The controller may determine that the fluid pump is associated with a leak of a particular severity level based on the torque data indicating a deviation that satisfies a first threshold, the speed data indicating a deviation that satisfies a second threshold, and the pressure data indicating a deviation that satisfies a third threshold. The controller may perform at least one operation based on the particular severity level of the leak.

Abstract: A control system of an engine is provided. The control system includes an inlet sensor configured to generate a signal indicative of an engine inlet air temperature and an intake manifold sensor configured to generate a signal indicative of an engine intake manifold air temperature. The control system includes a control module communicably coupled to the inlet sensor and the intake manifold sensor. The control module is configured to determine the engine inlet air temperature and the engine intake manifold air temperature. The control module is configured to determine an initial de-rate value based on a predetermined relationship between the engine inlet air temperature and the engine intake manifold air temperature. The control module is configured to determine a pre-stored de-rate modifier corresponding to an engine speed. The control module is configured to determine a final de-rate value based on the initial de-rate value and the pre-stored de-rate modifier.

Abstract: In some implementations, a controller may obtain a setting for a target discharge pressure associated with a fluid pump driven by a motor that is controlled by a variable frequency drive (VFD). The target discharge pressure may be for use in a pressure test of a system that includes the fluid pump. The controller may determine a target torque for the motor that achieves the target discharge pressure. The controller may cause, via the VFD and in connection with the pressure test, adjustment to a speed of the motor to achieve the target torque for the motor.

Abstract: In some implementations, a controller may monitor an available power supply of at least one power source for a system for hydraulic fracturing, and a current power demand of the system. The controller may determine, based on monitoring the available power supply and the current power demand, whether a relationship between the current power demand and the available power supply is indicative of an impending power failure. The controller may cause, based on determining that the relationship between the current power demand and the available power supply indicates the impending power failure, reduction of flow rates of one or more fluid pumps of the system to reduce the current power demand.
