Because real waves contain numerous harmonicwave and even exponentially. attenuating components, the accuracy of an algorithm depends on its filterability.
但由于实际波形中含有大量的谐波分量甚至指数衰减分量，直接影响了这些算法的精度。

Active power Filter (APF) technology is one of the important ways to realize harmonicwave compensation of electrical network and improve the quality of power supply.
有源电力滤波器(简称APF)技术是一种实现电网谐波补偿、改善供电质量的重要方法。

The harm of the high degree harmonicwave in power system was introduced and the selection of prevention and the measure of controlling the harmonic interference were put forward.
