Abstract
A method of controlling a high-pressure system having an engine, and a hydraulic pump having a swashplate includes inputting a maximum discharge pressure, a maximum allowable equipment pressure, a pressure relief valve (PRV) setting, a flowrate, and a maximum positive and negative rate of change of pressure; setting a work value to full power; setting a first position of the swashplate based on flowrate; determining: (a) if a discharge pressure is greater than the PRV setting; (b) if the discharge pressure is greater than the maximum allowable equipment pressure; and (c) if a rate of change of pressure is greater than the maximum positive rate of change of pressure or the maximum negative rate of change of pressure; and upon the occurrence of any of steps (a)-(c): (d) activating a PRV in the system; (e) setting the swashplate position to neutral; and (f) reducing the power to zero.
