Abstract
A pump system may include a hybrid powertrain that includes a gaseous fuel engine, a transmission coupled to the gaseous fuel engine, a driveshaft coupled to the transmission, a hydraulic fracturing pump coupled to the driveshaft, and a motor system coupled to the hydraulic fracturing pump. The pump system may include a power source electrically connected to the motor system. The pump system may include a controller configured to determine a torque distribution between the gaseous fuel engine and the motor system based at least in part on whether a transient event is associated with the pump system, and cause the gaseous fuel engine and the motor system to operate according to the torque distribution such that the motor system assists or brakes the gaseous fuel engine in driving the hydraulic fracturing pump.
