摘　　要：围绕快速晶闸管的混合式直流断路器的建模与控制进行研究。综合考虑不同控制策略下的故障电流迁移条件,提出了基于有限状态机方法的控制策略,实现不同状态之间相互转换,重点对预合闸控制和重合闸控制的实现过程进行了详细的状态切换分析和实现,通过将原来时序逻辑关系融合到不同状态的设定中,从而能够随时快速响应不同的事件,避免了传统时序控制方式必须完整执行全部控制过程导致的重复判断和交叉干涉。最后搭建了基于状态机下直流断路器控制系统,并对不同故障模式下的直流断路器状态切换进行了仿真,验证了采用有限状态机控制下多状态间的可靠、快速运行。The modeling and control of hybrid DC circuit breaker with the fast thyristor were researched.Overall considering the migration condition of fault current under different control strategies,a control strategy based on finite state machine method was proposed to implement the interconversion among different states.The realization process of pre-closing control and reclosing control was emphatically analyzed in detail and by means of fusing original temporal logic relation into the setting of different states thereby different events could be rapidly responded at any moment,and the repeated judgment and cross interference due to the fact that traditional time sequence control mode had to completely execute total control process could be avoided.Finally,a DC circuit breaker control system based on the state machine was built,and the status switching over of DC circuit breaker under different fault modes was simulated to verify reliable and fast operation among multi states under the control of finite state machine.
