Summary
DC Circuit Breakers (DC-CB) are a key enabling technology for multi-terminal High Voltage
Read more Read lessDC (HVDC) systems, as well as improving the performance of point-to-point overhead line systems. Primarily, these devices are installed to provide selective protection in the case of DCside faults, allowing the healthy areas of the system to continue operation. DC-CB operation generates a Transient Interruption Voltage, typically around 1.5 p.u. of system nominal voltage, to suppress fault current. Whilst this is required for fault current interruption, a lower TIV can be utilised to interrupt load current – as may be needed for reconfiguration operations on-line.
This paper investigates operating the DC-CB at partial TIV and the potential benefits.
