基于模糊规则的SSSC智能控制器设计

Design of SSSC Intelligent Controller Based on Fuzzy Rule

静止同步串联补偿器SSSC是FACTS中新型的串联补偿元件,它的快速、灵活控制特性及其在提高电力系统暂态稳定性上的作用具有广阔的应用前景。在模糊控制理论及数字PID控制方法的基础上,采用基于模糊理论的PI控制策略对SSSC的控制器进行设计,提出了基于模糊规则的SSSC智能控制器的设计方案。最后,利用MATLAB语言中的仿真环境Simulink对所设计的控制器进行了仿真验证,仿真结果证明:该控制器能够更有效地提高SSSC的控制性能,改善系统的动态特性。

The SSSC is a new series compensation component of the FACTS family. Compared to TCSC, the SSSC has faster and more flexible control characteristic and better effect on improving the transient stability of Power System and will have a promising prospect. We advanced the design project of the SSSC controller by analyzing the theory of fuzzy control and PID control, and adopt self-tuned PI control based on the fuzzy theory. Finally, we used the simulation model of MATLAB to validate the PI controller we designed, and gained the result. The PI controller we designed can improve the control capability and the stability of the power system.
