摘要
介绍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。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。
Based on instantaneous reactive power theory, the following paper introduces an improved harmonics current testing method. It can test harmonics current in a state of unbalanced grid and let active filter only compensate harmonics current in the works. This method also fits for harmonies current testing in a state of balanced grid.
