摘　　要：为了降低磁控电抗器MCR产生的谐波对电网的影响,笔者提出将MCR工作铁心设计为分级磁阀结构,并建立了这种铁心结构的磁路等效数学模型。在分析一般磁控电抗器谐波分布特性的基础上,给出了分级磁阀结构电抗器的谐波抵消原理。计算结果表明分级磁阀结构电抗器将现有MCR半极限饱和条件下输入电网的最大谐波电流含量由6%降低到3%。In order to reduce the harmonic generated by magnetically controlled reactor, a novel structure named multi-stage MCR was proposed. A magnetic circuit equivalent model of the multi-stage MCR was set up. The mechanism of self-harmonic suppression was analyzed. The calculation result shows that the proposed multi-stage MCR greatly reduce the generated harmonics without the assistance of external additional LC filters, reducing the five-order harmonic current from 6% to 3% in the case of half-rated-saturation.
