Abstract: Systems and methods for adjusting the power provided by an electric drive system to an ESP motor through an electrical network based on a model of the system and real-time inputs indicating operating conditions of the system. Some embodiments use a field oriented control system to adjust a direct-axis current setting to generate output power signals which drives the motor at a desired operating point for optimized performance. The electrical network may include a filter, a transformer, and a transmission line. A drive controller may receive real-time operating conditions and motor parameters as input, and may select further system parameters based on the received parameters. The controller builds a model of the electrical network and generates adjustments to the power generated by the drive using the system model and received real-time input. The adjustments may be recalculated at scheduled intervals.

Abstract: A method for implementing asynchronous operation of a permanent magnet motor (PMM) by detecting asynchronous operation of the PMM and creating cyclic variations in the PMM output using the asynchronous operation of the PMM. In another embodiment, an apparatus that comprises a microcontroller that obtains computer executable instructions stored on a non-transitory medium that when executed by the microcontroller causes the apparatus to determine that a rotor shaft within a PMM is rotationally restricted and to vary a plurality of frequencies and a plurality of amplitude currents supplied to the monitor to produce a reverse impact on a downhole tool coupled to the PMM.
