Over the last 60 years High Voltage Direct Current (HVDC) power transmission
has gained serious popularity; suggesting a valid alternative to the currently,
almost exclusively used, AC power transmission. The technological innovations of
the last 20 years on the electrical converters made HVDC an even more promising
solution on energy distribution and transmission. A lot of work has been done on
the area resulting in several examples of HVDC systems in the last three decades. There are still a number of problems in the technology if we want to talk about DC grids. The main issue is the interruption of the short circuit current in order for the line to shut down when a problem occurs on the grid. DC breakers are the key factor for the accomplishment of a function DC grid. There are currently several types of circuit breakers under research but a lot of issues still arise when it comes to their implementation. This report will summarize the technological attempts on DC breaker on the last 20 years, trying to weigh the advantages and drawbacks and conclude to an optimal suggestion for the future of this project.
