Harmonic filtering for the offshore industry

The application of a large number of adjustable speed drives (ASDs) operating electric submersible pumps (ESPs) on two separate offshore platforms, which are connected to a limited electrical power system on a tanker feeding power to the platforms via subsea power cables, produces high levels of harmonic distortions that can affect the overall system reliability. Such a system is described and discussed in detail and practical solutions to the problems are illustrated. The design of the harmonic filters has a major impact on the overall operation of the power system.<
