Sucker-rod pump unit electric drive simulator

Abstract

The sucker-rod pump unit (SRPU) electric drive simulator realized on the hardware-software complex of the National Instrument Corporation is discussed. The hardware-software complex includes a field programmable gate array (FPGA) module and programming tools. The simulator consists of pump-jack, power semiconductor converter and induction motor models operating in the real time scale. A SRPU control station can receives from the simulator such data as motor current, dynamometer card, wattmeter card, rotation speed, swing frequency, daily oil productivity of well and so on. That is why the simulator may be used for adjustment and diagnostics of SRPU control stations. Benefits of such approach are examination and adjustment of the control station conducting outside the oilfield or without stopping a pumping process.
