| 摘 要： | 提出了一种基于瞬时无功功率理论的改进的谐波电流检测方法，可以在电网不平衡状态下检测出谐波电流，而不会把基波负序电流与谐波电流同时提取出来，便于工程中有源滤波器只对谐波电流进行补偿。该方法也适用于电网平衡时的谐波电流检测。

| Abstract: | An improved method based on the theory of instantaneous reactive power for detecting the harmonic current is put forward ' which can check out the harmonic current from the grid under the unbalanced co conditions and not picking the base negative current out at the same time' and i s useful for the compensation of harmonic current in engineering. The method als o can be used for detecting the harmonic current under the balanced grid. |
