有源电力滤波器中谐波电流检测的研究，一篇学术论文，还是有比较大的参考意义。-Research on harmonic current detection of active power filter, an academic paper, or a larger reference value.

基于瞬时无功功率算法的谐波电流检测算法，有很好的谐波检测效果-Based on the instantaneous reactive power algorithm of harmonic current detection algorithm

这是基于快速傅里叶变换之后，计算电压，电流，有功，无功及谐波的算法。-This is based on the fast Fourier transform, the calculation of voltage, current, active power, reactive power and harmonic algorithm.
