摘要
直流可控电抗器是无功补偿的重要装置,但其本身由于磁化曲线的非线性特性会产生大量谐波。为改善其性能,提出了一种基于电流型有源滤波器的低谐波直流可控电抗器,其基本结构是在传统的直流可控电抗器的交流侧增加谐波补偿绕组。电流型有源滤波器检测出可控电抗器输入电流中的谐波分量,并产生与此谐波电流大小相等方向相反的补偿电流,通过补偿绕组耦合到可控电抗器的输入电流中,从而使输入电流接近正弦。文中讨论了这种低谐波直流可控电抗器的结构、工作原理及控制原理,并通过仿真分析进行了验证。
This paper presents a design of harmonic free direct current controllable reactor for single phase based on current-source active power filter（APF）. The novel controllable reactor adds harmonic elimination windings to APF to compensate the harmonic components of the input current. In this paper, the configuration, the working principle and the control method of the novel controllable reactor are discussed. The feasibility of the scheme is verified by simulation analysis.
