Abstract 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 but only two three terminal systems have been realized. For the acceptance and reliability of these networks, the availability of HVDC circuit breakers CBs will be critical, making them one of the key enabling technologies.
Circuit breaker design pattern
The DC hybrid circuit breaker based on high-speed switch HSS and parallel connected capacitor has been widely applied in the fault current breaking of DC system. However, when the current is commutated from HSS to the capacitor according to single-stage operation, the capacitor has to absorb a large amount of energy stored in the system inductance within very short time. Meanwhile, a high over-voltage rate of rise is especially prone to be produced between the contacts of HSS, which will lead to a failed breaking.
