基于模糊自整定PI控制的SSSC潮流控制器研究

在介绍静止同步串联补偿器(SSSC)的模型及控制结构的基础上,提出了一种模糊自整定PI控制的SSSC潮流控制器,设计了控制器的结构,建立了模糊控制规则表,进行了数字仿真.该控制器在动态过程中,利用模糊逻辑对SSSC的有功控制器和无功控制器的PI调节参数进行在线调整,提高了控制器的自适应能力和鲁棒性.仿真结果表明,该控制器具有比常规PI控制器更快的潮流调节速度.

Investigation of a Power Flow Controller of SSSC Based on Self-Tunning PI Controller with Fuzzy Logic

Based on the model and the structure of static sychronous series componsation (SSSC), this paper presents a new power flow controller of SSSC using fuzzy self-tunning PI control strategy, and build the relative fuzzy rules. In dynamic process, PI parameters of the real power and reactive power controller are on-line adjusted by using fuzzy logic. Thus, this controller has good adaptability and robust. Simulations show that adjusting speed of the power flow using fuzzy self-tunning PI control strategy is faster than the one using traditional PI controller.
