| Abstract |
In future HVDC systems, many DC circuit breakers (DCCBs) will be required. In this paper, an advancedtest circuit for DCCBs is described. A DC source is combined with a capacitor bank. In contrast to othertest circuits, the proposed test circuit allows to replicate constant DC and temporary faults. In additionto conventional faults, this enables testing of auto-reclosing, proactive commutation, and complex testsequences combining all of these modes. The test circuit is easy to setup and also suitable for smallerresearch facilities. Experimental results from a down-scaled mock-up are included to demonstrate thecapabilities of the test circuit. |
