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.
