摘　　要：双级饱和磁控电抗器(TSMCR)的工作铁心中含有2个长度和截面积都不相等的铁心柱,合理设计各铁心柱的长度和截面积,可有效减小TSMCR在动态调节过程输出谐波电流的大小。通过对TSMCR结构特点的分析,引入了2个关键设计参数:2个铁心柱的截面积比和长度比,并利用这2个参数建立了TSMCR的一般化数学模型。在该数学模型的基础上,对不同设计参数下TSMCR输出谐波电流大小的变化趋势进行了分析。研究发现在不增加任何额外滤波装置的条件下,当2个铁心柱的截面积比为1.9且长度比为0.37时,TSMCR在整个工作过程中输出谐波电流的大小都不超过额定基波电流的3.61%。为了进一步验证以上理论分析的正确性,建立了TSMCR的仿真模型并详细阐述了TSMCR的仿真技术,另外还对TSMCR样机进行了测试,仿真、实验结果都和理论分析相符,验证了TSMCR数学模型的正确性和谐波抑制方法的有效性。The iron cores of TSMCR（Two-stage Saturable Magnetic-valve Controllable Reactor） have two sections with different areas and lengths and their proper design can reduce the output harmonic currents during the dynamic adjustment.The generalized mathematical model of TSMCR is established by introducing two parameters：area ratio and length ratio.The harmonic current variation along with its parameters is studied,which shows that,without any additional filters,the harmonic current of TSMCR is lower than 3.61 % of rated fundamental current when area ratio is 1.9 and length ratio is 0.37.The simulation technique is introduced to TSMCR and a prototype is constructed and tested.Both simulative and experimental results are consistent with that of theoretical analysis,which validate the correctness of the mathematical model and the effectiveness of harmonic suppression method.
