A data acquisition system for electric submersible pump based on LabVIEW

LabVIEW virtual instrument field programmable gate array (FPGA) is applied to the real-time data acquisition of electric submersible pump parameters of voltage and current. The sampling data are analyzed by computer system, then apparent power, active power, reactive power and power factor are obtained, and those data are compared with those detected by power quality detecting instrument. The hardware of the system is NI sbRIO-9606 combined with NI9683 sandwich plate, and the combination breaks through the hardware acquisition on DAQ assistant tradition. Based on field programmable gate array (FPGA), the data acquisition system consists of a software acquisition chip and it has strong controllability, high accuracy and good applicability. Experiment shows that it can sample the data exactly and keep system errors in an allowed scope.
