摘要
根据单独注入式有源电力滤波器的分频控制的原理,分析了最基本的快速傅立叶变换FFT谐波分频检测、基于瞬时无功理论的iq、ip法检测任意次谐波,基于最小二乘法的谱估计法对谐波进行分频检测,通过试验与仿真对上述三种方法进行了比较,得到了有益的结论。
Fast Fourier Transform Algorithm and ip.iq Algorithm and Spectrum Estimation in harmonics detection of separate frequency are analyzed combining with the characteristics of APFSIC, and obtained the practical conclusion by experiment and simulation.
