    Abstract: A method and apparatus are provided for controlling the operation of a centrifugal pump, featuring steps of either adjusting the operation of the pump, or issuing a warning to a user of the pump of an undesirable operating condition, or both, based on a comparison of an actual torque value and a corrected torque value. The corrected torque value includes a Best Efficiency Point (BEP) torque value that is compensated for based on at least the current operating speed of the pump. The pump has a controller for performing the steps of the method, which can compensate the corrected torque value based on the square of the speed change of the pump, based on a mechanical power offset correction. The comparison includes a ratio of the actual torque value to the corrected torque value.

    Abstract: Disclosure is made of a method for electronic polar attenuation of torque profile for positive displacement pumps by a processor where the attenuated torque profile is compared with the shaft displacement angle of the pump input shaft. The processor then signals a motor to power a pump with the result of pumping at a constant pressure at the full range of the designed system flow volume. In addition to the attenuated torque profile, the processor can also account for the response time of the pump drive, the motor inductive reactance, system inertia, application characteristics of the pump, and regenerative energy during deceleration of the pump.

    Abstract: A method and system for determining the pump fillage of a sucker rod pumping system using torque feedback when pumping wellbore fluids from the particular well on which the sucker rod pumping system is installed. During the pump stroke, a microprocessor samples torque of the pump's mechanical system at an associated horsehead position at regular intervals and once the stroke is completed the raw torque samples and associated horsehead positions are placed in an array, the array of raw torque samples and horsehead positions can be filtered by the microprocessor into a second filtered array and then converted by the microprocessor into a rotatum array (derivative of torque with respect to time) of one or both of the raw or filtered arrays and stored as a rotatum array. The down stroke portion of the rotatum array is then analyzed by the microprocessor to determine the horsehead position when the piston of the down hole pump encounters wellbore fluid in the well (pump fillage). The microprocessor, based on the determined pump fillage, adjusts the speed of the pumping system to maintain an optimal pump fillage determined to be the most economical for the particular well on which the sucker rod pumping system is installed.
