Abstract
A method of controlling a pumping stage of a fracturing fleet at a wellsite with at least two electric frac pumps to increase the efficiency of the electric frac pumps comprises communicating an interim flowrate to the electric frac pumps and calculating an efficiency value from measured power from the VFD and measured flow rate, intake pressure, and discharge pressure. The method can increase a total efficiency of the fracturing fleet above a threshold efficiency value by iterating the interim setpoint from a first interim setpoint to a second interim setpoint for the electric frac pumps, wherein the second interim setpoint decreases the flowrate to the less efficient electric frac pumps and increases the flowrate an equal amount to the more efficient electric frac pumps.
