摘要: 针对由于低压单相用电设备增多造成电力系统中局部电流波形发生严重畸变的问题，设计了一种在低压系统中使用的单相谐波治理系统。该系统采用瞬时电流检测控制方法检测电流谐波含量，使变流器产生一个与电流谐波幅值相等、相位相反的电流分量，完全抵消系统中的电流谐波。实验结果表明，该系统补偿效果良好，使得谐波畸变率从治理前的76.3%下降到10.4%。

Abstract: In view of problem of severe distortion of local current wave caused by increase of low-voltage single-phase electrical equipment, a kind of single-phase harmonic suppression system used in low-voltage system was designed. The system uses instantaneous current detection control method to detect current harmonic content, so that the converter generates a current component which has the same amplitude and opposite phase with current harmonic, and can fully offset system current harmonics. Experimental results show that the system has good effect of compensation, and makes harmonic distortion rate fall from 76.3% to 10.4%.
