ABSTRACT This paper presents the outcomes of laboratory experiments intended to investigate the power quality of electrical submersible pumps (ESPs) with permanent magnet motors (PMMs) and those with induction motors (IMs). The tests involved two types of variable speed drives (VSDs): regulated DC bus voltage (six-step VSDs) and unregulated DC bus voltage (pulse-width-modulated VSD), with and without input filters, to determine the most effective surface configuration to achieve high power quality related to equipment efficiency. The objective of this study was to understand the power quality difference between induction and permanent magnet motors; surface configurations and equipment settings (VSD, presence of sine wave filters, harmonic filters, etc.) also play an essential role on power quality. Optimal system efficiency should lead to best pump, motor, and electrical efficiencies to enhance the daily operation and lengthen the overall run time via power quality reliability. Testing was performed with different motor loads and revolutions per minute (RPMs) on Both types of motor, induction and permanent magnet. Two types of VSDs were tested, one with six steps and the other with a pulse-width-modulated filter (PWM). Notably, these VSDs have various modes to regulate the voltage on the DC bus. Testing also included different scenarios with and without harmonic input filters.
