Abstract
High Voltage Direct Current (HVDC) short circuitprotection is a fundamental requirement for any HVDCtransmission system. Presently, all point-to-point links areprotected using circuit breakers on the AC side of theconverters. In order to enable HVDC grids, a more advancedprotection system must be developed. HVDC circuit breakersare one solution for the protection of future HVDC grids.Several designs have been proposed for DC circuit breakers butfew are suitable for Voltage Source Converter (VSC)applications. To date, only a few industrial prototypes have beendeveloped, which are seen to be suitable for the VSC HVDCapplications. This paper presents analysis and simulations onone of these prototypes, the Proactive Hybrid Circuit Breaker(PHCB). Equations are derived from a state-space analysis ofthe circuit breaker. A model of the circuit breaker is suitablyparameterized for a +/- 300 kV VSC system in PSCAD. Faultsimulations are then performed and compared to the equationsdeveloped in a state space analysis. Discussion is then given tothe design and testing of the Load Commutation Switch (LCS).
