摘要： Downhole tractor control systems and methods to adjust a load of a downhole motor to drive one or more wheels of the downhole tractor are disclosed. A method to adjust a load of a downhole motor includes receiving a user input of a desired speed and torque for a plurality of motors, where the plurality of motors powering rotation of wheels of a downhole tractor. The method also includes determining a minimum actual motor speed of the plurality of motors. For at least one motor of the plurality of motors, the method includes determining a power controller output and determining a torque controller output. The method further includes adjusting a voltage source invertor based on a lesser of the power controller output and the torque controller output to modulate voltage provided to the at least one motor.

摘要： Downhole tractor control systems and methods to maintain a load among multiple tractors are disclosed. A method to adjust a load among multiple tractors includes receiving first power feedback of a first downhole tractor, receiving second power feedback of a second downhole tractor, identifying an unbalance load condition when a difference between the first power feedback and the second power feedback exceeds a predetermined threshold, and adjusting, in response to identifying the unbalance load condition and based on the difference, power reference of the first downhole tractor and the second downhole tractor.

摘要： Downhole tractor control systems and methods to maintain a load of a downhole tractor are disclosed. A method to maintain a load of a downhole tractor includes identifying a reduction of power of a first set of motors of a plurality of motors of the downhole tractor, determining whether the reduction of power of the first set of motors is below a first threshold, and increasing, in response to the determination, a first power limit of a second set of motors of the plurality of motors to a maximum acceptable power limit of the second set of motors while maintaining the load of the downhole tractor.

摘要： An electrically powered artificial lift system includes a tubular for conveying a wellbore fluid upward and a downhole pump that urges the wellbore fluid into the tubular. A power cable conveys a three-phase power signal to the pump motor on three conductors. One of the three conductors is coupled to an internal node of a high-to-low voltage (HLV) source coupler via a low frequency blocking filter that shields the internal node from the motor power signal while conveying a sensor power signal from the internal node to the selected conductor and conveying a telemetry signal from the selected conductor and to the internal node. A similar downhole coupler couples a wye point of the motor to a downhole sensor assembly to supply the sensor power signal and to receive the telemetry signal.
