HVDC circuit breakers for HVDC grid applications
11th IET International Conference on AC and DC Power Transmission, 2015High Voltage Direct Current (HVDC) transmission has been expanding due to rapid development of power electronics technology and by the need for connection of offshore/remote wind farms and large hydro power generators. An HVDC grid will be required to operate the healthy lines continuously, even if a voltage collapse occurs at the remote end.

Development of HVDC Circuit Breaker and its Interrupting Test
IEEE Transactions on Power Apparatus and Systems, 1982The authors have developed a DC circuit breaker (DCCB) which interrupts a DC current by injecting a high-frequency reverse current from a commutating capacitor to be superposed to DC current and forcibly creating a current zero point. A breaking part consists of a vacuum interrupters or a SF6 gas, interrupters of the most advanced design connected in ...
