High Frequency Effects of Variable Frequency Drives (VFD) on Electrical Submersible Pump (ESP) Systems

Variable frequency drives (VFD) and subsea (umbilical) cables are frequently used in electrical submersible pump (ESP) systems for offshore platforms. There are two basic system configurations for ESP systems; VFD can be installed on the platform and the motor is connected to it through an umbilical...
