Abstract

This paper presents simplified and generic models for three DCCB topologies: hybrid DCCB, active current injection DCCB and VARC (VSC assisted) DCCB.
The generic model has identical structure for all topologies, but topology-specific parameters. This generic modeling approach simplifies DC grid studies and enables fast comparison between different DCCB topologies and protection system configurations. Simulation results on a DC grid model in PSCAD indicate that generic DCCB model gives accurate basic variables (peak current and voltage) for all topologies. The simplified models show very good accuracy for most variables but may not be able to represent internal component stresses. The comparison between simulation times indicates significant benefit in using generic and simplified DCCB models over the more detailed counterparts.
