Managing harmonics and resonance with active harmonic filters in an offshore ring main oil field

摘要

An international oil company acquired and modified the power supply for a number of offshore oil platforms in one field to conserve operating costs for fuel for the generators. This was accomplished by installation of a 33 kV undersea cabling system between the platforms. The resultant harmonic voltage distortion at the generators and on each platform created major safety concerns due to the explosion proof environments on the platforms and the large voltage resonance potential.
