滑窗迭代DFT法APF直流侧稳压控制研究
Research on DC side voltage control strategy of APF based on sliding-window iterative algorithm of DFT
摘要
Abstract
The active power filter ( APF) is a novel method of dynamic harmonic suppression .The compensation per-formance of APF is determined by the link of detection and control .At the same time , the DC voltage balance control is the prerequisite for APF to work normally .The detection method of harmonic current based on sliding-window itera-tive algorithm of DFT is introduced in this paper .And a DC side voltage control strategy is proposed based on each phase split current .The design method of PI parameter for voltage loop from the perspective of power balance , there-fore, the simulation model is set up and the experimental prototype is designed .The correctness of sliding-window it-erative algorithm of DFT and proposed DC side voltage control strategy is verified by simulation and experiment .关键词
