Because all the world is not at the same

frequency, ABB PCS100 SFC technology has been developed to bridge the gap in todays industry environments where equipment has different voltages and frequencies. It provides the economical solution for converting power to and from 60Hz and 50Hz frequencies.

Oil and gas operations are mostly situated in

merciless locations, from the intense forces of the arctic to the sweltering heat of deserts and hazardous conditions on the exposed open seas.

To sustain and secure operating environments in

these remote areas, reliable and stable power is crucial. ABB's PCS100 technology has recently been installed to improve the performance of the remote global offshore oil and gas industry operations based in the Congo. Two PCS100 1650kVA static frequency converter (SFC) units were commissioned in October this year, to shift power to and from 60Hz to 50Hz frequencies, linking LPG floating storage and offloading vessel

N'KOSSA II with its connecting production

platform. This multi-billion dollar industry is heavily reliant on maintaining continuous and efficient operations of its drilling equipment, pumping systems, and refrigeration functions at the production site. Equipment must be sufficiently robust to withstand extreme conditions; flexible to support multiple services; and be cost effective to lower capital expenditures and operating costs.ABB's power converter product range represents a quantum leap in high power technology, particularly in relation to it's technical performance and economic operation. The PCS100 SFC is a proven, efficient and effective power system that is specifically designed to interconnect incompatible networks. The PCS100 SFCunits installed replaced former technology to give a highly reliable system that is a more flexible, efficient, and cost competitive approach to supplying the frequency and voltage neccessary.

Key features and flexibility

ŮAbility to parallel with multiple generators

ŮHigh system availability throughadvanced

power module redundancy

ŮCapacity to provide output immunity toinput

disturbances (for voltage sags and frequency shifts)

Ů-The unity power factor rectifier with a

ŮTHDi of <3% provides lower harmonics

ŮAligned to inflexible space constraints

ŮMinimal operating and maintenance costs

ŮProtects sensitive and expensive loads

ŮClean sinewave output voltage

Typical applications

Ů50 to 60Hz or 60 to 50Hz industrial applications

ŮDockside converter - allows generators to be

turned off while at port to save fuel and elimi- nate pollution

ŮReplacement of motor generator sets

ŮAs a clean power supply to isolate an unstable grid from a critical load
