针对工业负荷大容量无功补偿和谐波抑制的要求,提出一种串联谐振注入式有源滤波器结合并联型无源滤波器的混合式滤波和无功补偿装置。详细讨论了装置的结构和滤波原理,同时通过对系统波特图的分析得出装置需要进行分频控制的结论。以此为基础,提出一种基于广义积分的模糊PI分频控制方法,介绍了其详细实现过程,并与其他控制方法进行了比较,仿真实验和应用表明,该方法能够有效地实现混合补偿装置的分频控制,在各方面都具有一定的优势。
In order to meet the requirements of large-capacity reactive power compensation and harmonic suppression of industrial load, a hybrid filter and reactive power compensation device with series resonant injection active filter and shunt passive filter is proposed. The structure of the device and the principle of filtering are discussed in detail. At the same time, the conclusion that the device needs to be divided and controlled is obtained through the analysis of the system bode plot. Based on this, a fuzzy PI frequency-division control method based on generalized integral is proposed. The detailed implementation process is introduced and compared with other control methods. The simulation experiment and application show that this method can effectively realize the hybrid compensation device The frequency control, in all aspects have some advantages.
