The operation of offshore drilling rigs and production platforms requires the extensive use of Variable Speed Drives. Historically this involved DC drives almost exclusively, but more recently, AC drives have begun to find their way onto these facilities. Often it is a combination of DC and AC drives that are used. Silicon Controlled Rectifier (SCR) or thyristor bridge based DC drives will distort...
In order to address concerns associated with electrical power system harmonic distortion on ships and off-shore oil platforms, marine regulating bodies have introduced strict new harmonic standards. These standards define the acceptable level of harmonic voltage distortion allowed on the vessels they certify. High harmonic distortion levels are appearing as a result of the increased use of power electronic...
Recent advances in power electronic drive converters have led to an increased use of this technology for electric propulsion and other variable speed drive applications on marine vessels such as ships and offshore oil platforms. The current and voltage harmonics these devices introduce however have caused marine regulating bodies to introduce strict harmonic voltage limits to ensure that the reliability...
