For several decades HVDC technology was used primarily for point-to-point bulk power transmission. Although multiterminal HVDC systems are very few in number, it is expected that multiple HVDC links may be interconnected into HVDC transmission grid. Since every meshed grid requires reliable protection solution, an HVDC circuit breaker must be developed and introduced. This thesis focuses on the performance evaluation of different HVDC circuit breaker concepts. The performance evaluation study is carried out by means of numerical simulations. The obtained quantitative results describe capabilities and limitations of different HVDC circuit breaker concepts as well as the reaction of HVDC network on switching operations. Different converter pr...
