| 摘 要： | 谐波分析是衡量电力系统供电质量的一个重要指标，简要地介绍了LabVIEW的背景、结构和特点，并详细地介绍了在LabVIEW环境下采用快速傅立叶变换FFT的谐波测量方法对谐波进行分析，得出总的谐波失真（THD）。此系统为实际电网中的谐波分析提供了一个良好的手段。

| Abstract: | Harmonic analysis is a major index in measuring the quality of power transmission.The background information,the structure and the characteristics of LabVIEW were introduced here,at the same time,a detailed demonstration of the process of harmonic analysis was given via FFT based on LabVIEW so that THD was obtained.Thus the LabVIEW provided a preferable means for the harmonic analysis in real power system. |
