摘要

谐波是在电力系统网络中产生电压和电流波形不对称的频率成分。现有用于量化这类谐波失真的标准指标，即总谐波(THD)和单个或谐波群分量的幅值和相位角，不足以完全表征它们对波形失真的影响。本文定义了表征电力系统波形中偶次谐波产生的不对称性的新指标，这些不对称性是偶次谐波特有的，依赖于它们的谐波阶数、幅值和相对于基波的相位角。

Characterization of even harmonics in power system networks

Even harmonics are frequency components that produce asymmetries in voltage and current waveforms in power system networks. The existing standard indices used for the quantification of this type of harmonic distortion, the total harmonic (THD) and magnitude and phase angle of the individual or harmonic group components, are not enough for the complete characterization of their effect in waveform distortion. This paper defines new indices for characterization of the asymmetries produced by even harmonics in power system waveforms, asymmetries specific to even order harmonics, dependent on their harmonic order, magnitude and phase angle with respect to the fundamental.
