| 摘 要： | 将滑动Goertzel DFT算法应用于有源电力滤波器的谐波电流检测,该算法具有计算量小、实时性好、易于工程实现等优点。有源电力滤波器的输出电流滞后于负载谐波电流,这会影响滤波效果。为了补偿这种延时提出了一种基于滑动Goertzel DFT的相位补偿算法。仿真结果验证了该算法的有效性和正确性。

| Abstract: | In this paper,the sliding Goertzel DFT algorithm is employed in the harmonic current detection of APF.This algorithm has low computational workload and good real time characteristics.It is also easy for the engineering implementation.The output current of APF always lags behind the load harmonic current,which will definitely affect the performance of APF.To solve it,a novel phase compensation algorithm is proposed here.Besides bearing the advantages of the sliding Goertzel DFT algorithm,it performs excellen... |
