Transmission and distribution
Power semiconductors are a key element in an increasing number of ABB products and systems taking a lead role in almost all electrical applications. Built into systems that allow higher power in existing grids and enable transmission with lower losses, they contribute to an efficient distribution of electrical energy. ABB’s semiconductors enable electrical energy up to 6 gigawatt (GW) to be transmitted through HVDC (high-voltage direct current) lines at 800 kilovolt (kV).
In FACTS (flexible alternating current transmission systems) power semiconductors help ensure stable grids and minimize reactive power.
For systems where better control possibilities are required, ABB has developed HVDC LightTM based on IGBT press-pack technology (StakPak modules). One example is the offshore wind farm Borwin1, in the North Sea. Featuring HVDC Light the offshore wind farm is capable to transmit 400 MW into the German grid.
ABB presents the first IGCT-based multilevel static frequency converter available on the rail market – Rail SFC Light provides following benefits:
- Maximum energy efficiency
- Real redundancy in the power-electronics
part makes it possible to design highly
- Robust converter design for
maximum safety in case of failure
- Excellent reaction to events in
the railway and utility networks
- Quick and very easy maintenance
