What makes ABB’s PCS100 SFC stand out?
|
Clean sinewave output voltage
|
The system is constructed of multiple power electronic modules and functions by converting the input AC power through a sine-wave rectifier to a DC link and then through an AC sine-wave inverter to produce a clean, full sine-wave output at the new frequency and voltage.

|
N+1 modular redundancy for mission critical applications
|
In an unlikely event where either a single rectifier or inverter module encounters a fault and stops functioning, the master controller that oversees the rectifier/inverter module pairs will reduce the output capacity to the available remaining working rectifier/inverter module pairs. The load will not be shed, but it will be transferred seamlessly to the remaining module pairs in the converter. Allows flexible planning of converter repair/faulty module replacement.

Parallel load sharing
|
The PCS100 SFC is extremely flexible with regard to paralleling with other voltage sources, either other generators or multiple SFC units. Parallel load sharing is achieved using frequency and voltage droop profiles programed into the converter. This allows the converters to share power with other systems without the need for any additional communication signals. In addition SFC converters of different power ratings can be paralleled, with each one delivering the same percentage of its rated power as required by the load.

Automatic Output Synchronization
|
Starting the SFC into the live bus is greatly simplified due to the automatic output synchronization feature. This enables a full seamless transfer from generator supply to SFC supply on the output bus. If the output bus is dead when the SFC is given a start command it will ramp up the voltage over one second, providing a soft energizing of the output.
