摘　　要：在实时性导通控制中,常用过零检测法和锁相环法。比较了过零检测法、三相单同步、三相双同步坐标系锁相环法,提出了适用于混合式固态交流断路器(Hybird Solid State Switch,HSSS)的单相自解耦锁相策略,并给出了数学模型和控制模型,通过分析稳态性能和动态性能得出了控制参数。在MATLAB/Simulink环境下构建上述实时性控制模型与HSSS模型,通过仿真与最优化分析验证了单相自解耦锁相环在各种电网电压工况下具有良好的锁相效果,能够实现HSSS的基本功能,满足实时性控制要求。Zero Crossing Detection （ZCD） and phase locked loop are widely applied in the real-time control. Compared the performances ofZCD, SSRF SPLL and DDSRF SPLL, a method named as Single Phase Self Decoupling SPLL （SPSD SPLL） for HSSS（Hybrid Solid State Switch） is proposed and the mathematical method and control methods are given. The control parameters were obtained by analyzing the steady and dynamic performance of SPSD SPLL. By establishing the real-time controlling models based on the above strategies and HSSS model in the MATLAB/Simulink, the simulation and optimization analysis results verified that the SPSD SPLL was well performed under different working conditions, the SPSD strategy could realize the basic functions of HSSS, and the requirement of real-time control could be satisfied.
