Innovative high-voltage switchgear key to subsea compression

Power EquipmentSubsea Switchgear Electrical System DesignElectromagnetic CompatibilityAuxiliary Power SuppliesProtection SystemInterface EngineeringThermal EngineeringMechanical DesignFabrication EngineeringAvailability StudiesThe pilot subsea gas compressor motor is rated 12.5 MW and is used together with a 400 kW pump. The long tieback makes subsea power distribution necessary. The equipment in the CBM is 36 kV class and the subsea system voltage is 22 kV. Auxiliary power is provided via a transformer and is backed up by an uninterruptible power supply (UPS) in a separate subsea module. Circuit breakers and protection devices that could operate within an oil-filled, pressure-compensated environment are not yet commercially available. The switchgear is in an enclosure that provides a 1-atm pressure environment. Dry nitrogen fills the enclosure. Its physical properties are close enough to air to allow standard electrical equipment to be used. The high-voltage (HV) circuit breakers are proven 36 kV class air-insulated devices.

High-voltage direct current - Wikipedia

High Voltage TransmissionHistoryComparison with ACCostsConversion ProcessConfigurationsCorona DischargeApplicationsAdvancements in UHVDCFurther ReadingHigh voltage is used for electric power transmission to reduce the energy lost in the resistanceof the wires. For a given quantity of power transmitted, doubling the voltage will deliver the same power at only half the current. Since the power lost as heat in the wires is directly proportional to the square of the current, doubling the voltage reduces the line losses by a factor of 4. While power lost in transmission can also be reduced by increasing the conductor size, larger conductors are heavier and more expensive. High voltage cannot readily be used for lighting or motors, so transmission-level voltages must be reduced for end-use equipment. Transformers are used to change the voltage levels in alternating current(AC) transmission circuits. Transformers made voltage changes practical, and AC generators were more efficient than those using DC. These advantages led to early low voltage DC transmission systems being supplanted by AC systems around the turn of the 20th century. Pra...Get price
