Pumping dynamic load analog control system design and development

Abstract

For special conditions pumping, in order to facilitate the measurement of energy-saving and efficient pumping efficiency motor, designed and developed in the laboratory simulation of pumping dynamic load control system using DSP data acquisition system, the motor is calculated in real time by the FFT algorithm power, combined with the PC software, the use of differential forward PID algorithm to control a DC motor to produce alternating torque load to simulate pumping motor pumping site conditions. Field test showed high accuracy system simulation can accurately measure the pumping efficiency of the motor under dynamic loads, provide an effective basis for the evaluation of pumping electrical energy has great value.
