Research on Harmonic Analysis System Based on Virtual Instrument

Shuo Ding

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.
