Superconducting Fault Current Limiters for HVDC Systems
Energy Procedia, 2015 AbstractHigh-voltage direct current (HVDC) transmission systems using Voltage-Source Converters (VSC) are widely recognized as offering significant potential for long distance high power delivery, particularly for offshore wind farm connections. One of the barriers for the development of multi-terminal HVDC systems is the lack of technologies which ...
