傅立叶算法能够滤除和抑制高次谐波的影响,然而受衰减的直流分量的影响很大,通常采用差分滤波的方法滤除衰减直流分量的影响,本文提出一种不受衰减直流分量影响的改进并联补偿算法,无需差分滤波,可以消除衰减直流分量的影响。仿真计算表明,与差分滤波相比,本算法对衰减直流分量有更好的抑制能力。
傅立葉算法能夠濾除和抑製高次諧波的影響,然而受衰減的直流分量的影響很大,通常採用差分濾波的方法濾除衰減直流分量的影響,本文提齣一種不受衰減直流分量影響的改進併聯補償算法,無需差分濾波,可以消除衰減直流分量的影響。倣真計算錶明,與差分濾波相比,本算法對衰減直流分量有更好的抑製能力。

The Fourier algorithm has the advantage of eliminating or restraining the affection of high frequency harmonics, however suffers the disadvantage of affection induced by DC decay components. Therefore, differential filter is used to eliminate the DC decay component without influence of DC decay component, before the measured signal come into the device. This paper describes an improved shunt compensation algorithm, which can natural y eliminate the affection of DC decay component without any filters. The simulation calculation shows that the proposed algorithm is better than the traditional processing method.
