Abstract: The paper studies control and protection strategy of mechanical HV DC circuit breaker (DCCB) in fault condition application in ±160 kV Nan’ao multi-terminal VSC-HVDC system. Firstly, fundamental principle of mechanical DCCB is analyzed and simulated. Secondly, all kinds of faults, possibly occurring and affecting multi-terminal VSC-HVDC system for mechanical DCCD under operation, is analyzed in detail, including abnormal switching-on, abnormal trip, failed switching-off and failed switching-on. And a control and protection strategy is proposed. Finally, the proposed strategy is validated with real-time simulations and field experiments. The simulation and experiment results show that the proposed control and protection strategy can ensure security of multi-terminal VSC-HVDC system under fault conditions of mechanical HV DCCB.
