FLUID EXTRACTION SYSTEM HAVING POWER CONTROL SUB-SYSTEM AND RELATED METHODS

摘要

A power control sub-system for controlling a plurality of electric machines disposed in a well is disclosed. The power control sub-system includes at least one power cable configured to conduct a direct current to and/or from one or more electric machines of the plurality of electric machines. The power control sub-system further includes a switching device disposed proximate to one or more of the plurality of electric machines in the well, where the switching device is electrically coupled to the at least one power cable and the plurality of electric machines, and where the switching device is capable of withstanding high temperatures and is configured to selectively control supply of the direct current to and/or from one or more electric machines of the plurality of electric machines. A fluid extraction system employing the power control sub-system and a method of controlling the plurality of electric machines are also disclosed.
