Combined operation system and strategy of solid-state current limiter and direct-current circuit breaker

The invention relates to a combined operation system and strategy of a solid-state current limiter and a direct-current circuit breaker, which are characterized in that through the designed combined operation system and strategy of the solid-state current limiter and the direct-current circuit breaker, a natural zero crossing point is provided for the direct-current circuit breaker by using the solid-state current limiter after the system breaks down; after the solid-state current limiter is matched with the direct-current circuit breaker, the current peak value and the fault current at the fault moment and the reclosing moment of the direct-current circuit breaker can be effectively restrained, the stability of the voltage of the outlet side of the converter station can be maintained, and the fault removal speed of the system is improved. And the power supply reliability of other ports of the system is ensured. 本发明涉及一种固态限流器与直流断路器的联合运行系统和策略，通过设计的固态限流器和直流断路器的联合运行系统和策略，利用固态限流器在系统发生故障后为直流断路器提供自然过零点，从而实现直流断路器的无弧关
