摘要：

针对托卡马克磁体电源无源滤波器运行特点，计算推导了单调谐和高通滤波器等效频率偏差工况下的阻抗特性，提供了一种基于低压高精度电压/电流的阻抗频率特性测量方法，通过ITER极向场电源测试用无源滤波器阻抗实验验证了该方法的有效性，所得结论可为ITER谐波抑制及无功补偿系统现场试验提供有益的理论和工程参考。

Abstract:

According to the operation modes of passive filters, the impedance characteristic of single-tuned and high-pass filter was deduced under equivalent frequency deviation, and a high-precision measuring method was proposed. The effectiveness of the two methods is validated during the experimental test of ITER poloidal field power supply. The conclusion would offer useful theoretical and engineering references for ITER reactive power compensation and harmonic filtering system.
