DEVICE, COMPUTER PROGRAM PRODUCT AND COMPUTER-IMPLEMENTED METHOD FOR BACKSPIN DETECTION IN AN ELECTRICAL SUBMERSIBLE PUMP ASSEMBLY |
摘要 |
A system for detecting a backspin condition of a motor in an electrical submersible pump is disclosed herein. The system comprises a sensor mounted proximate to the motor, the sensor outputting a signal, a power cable connected between a motor and a controller, the power cable supplying a three phase AC voltage to the motor, one phase of the three phase signal having a control signal thereon; electronics connected to the sensor, the electronics receiving the signal and propagating the signal to the controller; and a computer defining the controller, the controller having a non-transitory memory, a computer processor, and a computer program product stored on the memory and executable by the processor, the computer program product performing a process of controlling the variable speed drive of the motor and a process of monitoring the signal from the sensor to determine if the motor is backspinning. |
