5 Product description
Overview
The ABB SureWave SFC is a high-performance high-efficiency static frequency converter system
that provides a stable three-phase power supply with fixed voltage and frequency. The supply
source is likely to be of different voltage and frequency to that required by the load.
A typical application of a frequency converter is the supply of electrical power to a ship when it
is in harbor. The ship will be able to be supplied with electrical power without running any on-
board generators. This has major benefits in reduction of noise and pollution, reduction in run-
ning time of shipboard generators, and overall energy savings.
The SureWave SFC uses ABB’s new generation PCS120 power modules to convert the incoming
utility to DC, then convert this DC back to 3-phase AC for supplying the load at the required fre-
quency and voltage. The PCS120 power modules are compact and efficient, which contribute to
the overall SureWave SFC being a compact powerful converter system with a fast-dynamic re-
sponse to load changes and a high overload margin.
The SureWave SFC installation may be stand alone, operating the load without any parallel con-
nected generating capacity. Or it may be connected in parallel with an existing generator bus,
where it may be started to seamlessly take over the load from the generator(s). Alternatively, it
may be connected in parallel to one or more SureWave SFC. Each of these possibilities is best
catered for by selecting one of several operating modes.
