摘要
谐波测量在电力系统中占有重要的地位和作用。提出了一种基于虚拟仪器的谐波测量技术,采用快速傅立叶变换FFT的谐波测量方法,结合数据采集卡和PC机在L ab VIEW软件平台上开发虚拟谐波测量仪,为解决谐波分析与谐波抑制提供了依据。实验结果证明该仪器的可行性和正确性。
In power system the harmonic measurement plays an important part. The techniques of harmonics measurement based on virtual instrument are introduced, which could become a useful reference for harmonics analysis and suppression. According to the FFT method applied to measure harmonics in power system, a virtual harmonics measurement instrument is designed in LabVIEW environment combining with the data acquisition card and personal computer. The experimental results show the feasibility and correctness of the instrument.
