中文摘要:

介绍了基于虚拟磁链的有源滤波器直接功率控制工作原理,提出了一种针对于三相三线制有源滤波器的控制方案。该方案采用虚拟磁链进行定向,省去了常规电压定向所使用的电压传感器。利用矢量调制环节发出驱动脉冲,实现恒频控制。提出将模糊PI控制器应用于直接功率控制系统的电压控制环节,具有鲁棒性强和动态响应速度快等优点。仿真结果证实了本文所设计的基于虚拟磁链的有源滤波器直接功率控制系统的正确性和有效性。

英文摘要:

Principle of direct power control for active power filter based on virtual flux was introduced, and a new scheme for three phase three wire active power filter was proposed. In the scheme, virtual flux was used to oriented, and the use of voltage sensor in conventional voltage oriented was overlooked. As to attain frequency control , the driving pulse is produced by space vector pulse modulation(SVPWM)link. At the same time, the fuzzy PI controller is applied to the voltage control link of direct power control system with robustness and fast dynamic response. The simulation result showed that the designed of direct power control system for active power filter based on virtual flux in this paper was correctness and effectiveness.
