Filed:

May 9, 2008

Appl. No.:

12/118166

Inventors:

Chris M. Young - Austin TX, US
John A. Billingsley - Groesbeck TX, US
David L. Beck - Manor TX, US

Assignee:

Zilker Labs, Inc. - Austin TX

International Classification:

G05B 13/02

US Classification:

700 37, 700 42, 700 54, 700 55, 700 71, 323283, 715771

Abstract:

Complex filters may be used to achieve compensation of a plant, corresponding for example to a power regulator or point-of-load (POL) regulator. Digital filter coefficients may be mapped to analogous poles and zeros, or they may be mapped to values of the quality factor (Q) of the output, frequency, and gain. The plant may be observed and characterized using a network analyzer to generate the Bode plot (or Nyquist plot) for the plant. The digital filter coefficients may be mapped to features that may be identified on the Bode plot (or Nyquist plot) to easily correlate characteristics of the digital filter or digital compensator to the plant characteristics. The mapped features may be adjusted, for example by a user, either manually or by executing one or more optimization algorithms, to achieve the desired results relative to the Bode plot (or Nyquist plot). The mapped features may then be reverse mapped to the digital filter or digital compensator coefficients to fine tune and implement the digital filter or digital compensator.

International Classification:

G06F 1/26

US Classification:

700298, 323234

Abstract:

An auto-compensation method for compensating power regulators configured to generate a regulated output voltage. Auto-compensation may be performed dynamically by determining various coefficients of a compensation function used in compensating the power regulator, based on assumptions about the structure of the regulator and corresponding filters. The method may be used to determine at least the DC loop gain and the position of the compensation zeros, without requiring any prior knowledge of the values of the various components of the system. Furthermore, the selection of the compensation parameters (loop gain, position of zeroes) may be based on measurement of various state variables of the actual power converter, and adjustment of the various coefficients of the compensation function according to the measurements. Since no power-plant model of the power regulator is used, inaccuracies that would be inherent using any method that employs a model of the system instead of the system itself may be eliminated.

Abstract:

A system comprises an electric submersible pump (ESP) motor electrically coupled to a variable speed drive (VSD) that outputs voltage to the ESP motor. The system comprises a magnet on a shaft of the ESP motor and a downhole sensor coupled to the magnet, wherein the downhole sensor is to measure a magnetic flux of the magnet. The system comprises a VSD controller to control the VSD, wherein the VSD controller comprises a processor and a non-transitory memory storage having instructions stored thereon that are executable by the processor to perform operations comprising: obtaining a measurement of at least one pump performance variable and a motor current for a first period of time to establish a first data set and making a first adjustment to a voltage output from the VSD to the ESP motor, the first adjustment having a first adjustment type.

International Classification:

E21B 43/12
E21B 43/38

Abstract:

A system for protecting an Electrical Submersible Pump (ESP) string from gas slugs in a downhole well environment. The system comprises an intake tube having a first and second end and one of a packer having a bypass channel and an inverted shroud coupled to the intake tube and the ESP string. The intake tube is independent of a pump and a motor of the ESP string. The system can comprise a bypass tube for channeling the gas slug downstream of the pump. The bypass tube is integrated with the packer. The inverted shroud is coupled with the first end of the intake tube and a section of production tubing downstream from the pump and the motor. The inverted shroud forms a bypass path channel within a casing annulus.
