Design, test and application of HVDC circuit breaker

HVDC transmission is used for bulk power transmission over long distances, to interconnect asynchronous AC networks or for underground/submarine cable transmission with lengths above several tens of kilometres, e.g. in case of offshore wind power plant connections to the mainland.
In contrast to LCC-HVDC systems, systems based on Voltage Source Converter (VSC) technology assume an increasing role in worldwide grid developments to allow a more flexible operation and to be able to connect weak AC grids, such as networks dominated by renewable generation infeed. The VSC-HVDC technology enables the use of multi-terminal DC systems including meshed DC grids with multitude of converter stations and DC transmission lines.
