Methods and systems for operating a fleet of pumps

A system to control operation of a plurality of pump units associated with a hydraulic fracturing assembly, each of the pump units including a turbine engine, connected to a gearbox for driving a driveshaft, and a pump connected to the drive shaft, the system comprising:

• a controller in communication with the plurality of pump units, the controller including one or more processors and memory having computer-readable instructions stored therein and operable by the processor to:
• receive a demand hydraulic horse power (HHP) signal for the hydraulic fracturing assembly,
• based at least in part on the demand HHP signal, operate all available pump units of the plurality of pump units at a first output power to achieve the demand HHP;
• receive a loss of power signal from one or more pump units of the plurality of pump units,
• after receiving the loss of power signal, designate the one or more pump units as a reduced power pump unit (RPPU),
• designate the remaining pump units as operating pump units (OPU), and
• operate one or more of the OPUs at a second output power to meet the demand HHP signal of the hydraulic fracturing system,
• the first output power being in a selected range of a maximum continuous power (MCP) level of the plurality of pump units, the second output power being greater than the first output power and being in a selected range of MCP level to a maximum intermittent power (MIP) level of the plurality of pump units.
