Abstract

In the area of electric submersible pumps (ESPs), permanent magnet motor (PMM) drives are drawing increasing attention due to the advantages of high energy efficiency and high-power density. However, there are few studies focusing on the specific issues of the ESP PMM drives. To solve the issue, this paper emphasizes the voltage drop and position estimation inaccuracy issues of the system. First, the voltage drops caused by the LC filter, transformer, and long cables are analyzed, providing guidelines for designing the appropriate PMM drives. Second, the impacts of system structure on position and speed estimation accuracy are explained at length, posing necessity of developing improved sensorless control strategies. Finally, simulation is conducted on a PMM drive to verify the effectiveness of the analytical results.
