Multi-Port Hybrid DC Circuit Breaker for DC Distribution Network

2019 IEEE 8th International Conference on Advanced Power System Automation and Protection (APAP), 2019
The two-port hybrid DC circuit breaker (TP-HCB) combines the advantages of mechanical DC circuit breaker (DCCB) and solid-state DCCB, which has small loss during normal operation and fast action speed. However, the TP-HCB contains many IGBTs to withstand transient breaking voltage, therefore the total cost of TP-HCB is relatively high.

An Integrated Multi-port Hybrid DC Circuit Breaker

2019 IEEE 8th International Conference on Advanced Power System Automation and Protection (APAP), 2019
A massive number of hybrid DC circuit breakers (HCBs) have to be installed to protect a voltage source converter based multi-terminal DC (MTDC) system, leading to quite high costs. To reduce the implementation cost employing HCB in DC systems, this paper presents an integrated multi-port hybrid DC circuit breaker (IMP-HCB), which consists of an ...
