Abstract

Harmonic measurement plays an important part in power systems. In this paper, a brief introduction on sources and harms of harmonics is given. A harmonic measurement method based on interpolating windowed FFT is proposed and analyzed. According to the analytic results, a multifunctional virtual instrument system for harmonic measurement of voltage and current signals is designed and implemented in LabVIEW environment. Furthermore, the function of remote transfer of measured results is implemented using the AppletVIEW Toolkit in LabVIEW adopting a B/S framework. Measurement results show the feasibility and validity of the system.
