摘要： Subsea power supply assembly (10, 20) supplying electric power to a motor (11) at a second location (90) from a first location (80), comprising a variable speed drive (13) (VSD) and a step-up transformer (15) connected to it. At a subsea location the assembly comprises a first step-down transformer (17) with input (17a) and output (17b) and an uninterruptable power supply (25) having an input (25a). A step-out cable (19) supplies power from the step-up transformer (15) to the motor (11). The cable (19) connects to the first step-down transformer (17). The speed of the electric motor (11) is proportional to the output frequency of the VSD (13). The power receiving input (25a) of the uninterruptable power supply (25) connects to the output (17b) of the first step-down transformer (17), thereby receiving electrical power with frequency equal to the output frequency of the VSD (13).

摘要： A high voltage offshore power plant power distribution assembly (100) comprising, at a subsea location, two end transformers (10a) and one or more intermediate transformers (10b), wherein the respective end transformers and intermediate transformers comprise a housing (11), a transformer core and winding assembly (13) comprising a plurality of sets of utility windings (15) and a set of collection windings (17), a plurality of utility terminals (19) connected to utility windings, wherein at least some of the utility terminals are connected to offshore power providers (1, 3). A collection line (28) connects to the set of collection windings (17). The respective end transformers and one or more intermediate transformers further comprise two collection terminals (29) and a collection line branching (27) located inside the housing (11). The collection line branching (27) connects the two collection terminals (29) to the collection line (28).

摘要： Subsea power supply assembly supplying electric power to a motor at a second location from a first location. The subseas power supply assembly includes a variable speed drive (VSD) and a step-up transformer connected to it. At a subsea location the assembly includes a first step-down transformer with input and output and an uninterruptible power supply having an input. A step-out cable supplies power from the step-up transformer to the motor. The cable connects to the first step-down transformer. The speed of the electric motor is proportional to the output frequency of the VSD. The power receiving input of the uninterruptible power supply connects to the output of the first stepdown transformer, thereby receiving electrical power with frequency equal to the output frequency of the VSD.
