摘　　要：分析了中性线电流产生的原因,指出由于系统谐波导致中性线电流超载所带来的危害。介绍了零序谐波滤波器专用于治理零序谐波的基本原理。并通过应用实例,展示了采用零序谐波滤波器治理零序谐波电流的效果,说明采用零序谐波滤波器是解决系统零序谐波导致中性线电流超载问题的有效方案。The causes of neutral conductor current and the harmfulness of the neutral conductor current overload resulted from the system harmonic are studied. The basic principle for the zero-sequence harmonic filter exclusively for preventing zero-sequence harmonic is described. The effect of zero-sequence harmonic filter to prevent the current resulted from zero-sequence harmonic is illustrated with example applications, which show that preventing neutral conductor current overload resulted from system zero-sequence harmonic by using zerosequence harmonic filter is an effective scheme.
